Sound like libgphoto2 crash... check your system...

Which camera and libgphoto2 version you use ? Go to Help/Component Info for details...

New crash information added by DrKonqi

digikam (2.0.0-beta4) on KDE Platform 4.6.1 (4.6.1) using Qt 4.7.0

- What I was doing when the application crashed:

Reproducible in Digikam 2.0.0 beta3 and beta 4 but not in Digikam 1.9.

Attached camera to usb-port and selected Digikam 2.0.0 beta4 as program to open with. Also happen when using the import tool in Digikam 2.0.0 beta4 from the menu. There is no problem if Digikam is downgraded to Digikam 1.9 so the problem shouldn't be with libgphoto but how libgphoto is called in Digikam 2.0 beta 3/4, or something like that.

Philip,

There is no difference between 1.9 and 2.0 how digiKam call libgphoto2 API. No changes have been done here in source code.

So, it's probably a packaging issue.

Gilles Caulier

I have done more testing trying to see if this bug really is a packaging issue. Even if I build and install any of the 2.0 betas (2-4) with either cmake and no packaging tools I get camera gui crashes. If I build Digikam 1.9 there are no crashes.

The crash happens with all features that access the libgphoto2 (coincidences??) either when using import > camera or in accessing supported cameras to list them in settings > configure > camera or trying to add a camera in Digikam.

Camera gui works fine as it should if the camera function as a usb mass storage instead of libgphoto features.

I have tried different versions of libgphoto to solve this, 2.4.8 and 2.4.10.1. I have tried compiling them in versions using udev, HAL both or either of them but nothing matters as it crashes anyway. Digikam 1.9 works with any of the libgphoto version. I can also use gtkam or Dolphin to access the camera using libgphoto without any problems

Depending on if I access any feature that use libgphoto I get somewhat different crash logs. I'll attach them too if they give any clues.

Otherwise I use this setup with Digikam:

Exactly the same thing happens with Digikam 2.0 beta 4 when built on the Kubuntu 11.04 (natty) so it looks like the problem might be *ubuntu specific?!?!

On Kubuntu 11.04 the system components are these (newer version of QT4 from previous bug reporting in this thread):

New crash information added by DrKonqi

digikam (2.0.0-beta5) on KDE Platform 4.5.1 (KDE 4.5.1) using Qt 4.7.0

- What I was doing when the application crashed:
Plugin in camera.

From the drop down menu of the device notifier widget and select 'Download photos with digikam'

Digikam opened as expected and then crashed.  Happen with both a cannon powershot sd750 and a nikon d5000.  This log is for the cannon, I can provide the back trace for the nikon if you want it.

Also crashes trying to access the camera from with in digikam rather than launching from the notifier.

- Custom settings of the application:
digikam is compiled from git.  I can provide the exact configuration if requested.  I have pulled all the dependencies from the ubuntu repositories (10.10)

This problem also exists with the rc code compiled on arch linux so this is not a ubuntu specific issue.

per the suggestion in the mailing list from Pierre Hanser (http://mail.kde.org/pipermail/digikam-devel/2011-April/050653.html) starting digikam from the command line as:

[tcaswell@inara ~]$ LD_PRELOAD=/usr/lib/libusb.so digikam
libdc1394 error: Failed to initialize libdc1394

The error relating to libdc1394 is not generated without the LD_PRELOAD.

*** Bug 268773 has been marked as a duplicate of this bug. ***

It's definitively a problem from Gphoto2. digiKam do no use libdc1394... It's perhaps a packaging problem...

Gilles Caulier

I think this is a very strange problem as I have built Digikam 2.0 beta4 on
Ubuntu 10.10 and 11.04 and get this crash in libgphoto2/usb but it works
fine if I build it in Fedora 14. Digikam 1.9 on the other hand builds and
works just fine on all these three distros (including Ubuntu). So if it's a
packaging issue it's something that only happens when Digikam 2.0 (and not
Digikam 1.9) calls to initiate usb over libgphoto2 on Ubuntu but doesn't
happen in Digikam 1.9. It looks like cameragui(?) or something that backends
it is changed in Digikam 2. Maybe some obscure or tiny change that anyway
make this happen on at least Ubuntu. I haven't tried to build it on Debian
though.

This problem have nothing to do with my Digikam 2.0 packages as it happens
on Ubuntu even when it's not built as packages but use the cmake build and
install system. Not sure where to start looking either... :(

I'm sure : GPhoto2 backend from digiKam 2.0 CameraGUI is not changed with this release. It's the same code between 1.9 and 2.0

Gilles Caulier

I think the problem may come through the following path

    libkface -> libopencv -> gstreamer -> libdc1394

libopencv may be linked with gstreamer which calls 1394 functions.

the problem exist because there are public definitions duplicated between
libusb and libdc1394

$ nm -D /usr/lib/libusb.so|grep usb_init
00001180 T usb_init

$ nm -D /usr/lib/libdc1394.so.22.1.4|grep usb_init
         U libusb_init
0001f8d0 T usb_init

ubuntu uses an version 1 of libdc1394 where a version 2 exists

Yes this is the core of the problem. I'm not sure if it is possible to have
some kind of check in digikam if usb is initiated or not as this is the only
application that have this problem that i know of.

The problem happens if opencv is built with libdc1394 support. If opencv is
built without libdc1394 then libgphoto2 works with digikam and doesn't
crash. So it's the combination opencv with libdc1394, libgphoto2 and digikam
or maybe opencv and libgphoto2 that gives crashes with usb initiation. I
guess that opencv is built without libdc1394 support/dependency on fedora
and mandriva?!

So my question is: is this a upstream problem for opencv, libgphoto2 or
digikam or a packaging problem that must turn off libdc1394 support in
opencv for all possible application to use it?

I think the core of the problem is in libdc1394: looking at the code,
it looks like it can use various internal backends, one of which being
usb. So the symbol usb_init is not intended to be public! The library
leaks internal symbol...

There are various solutions, one which which is not a real solution
but which involves only digikam would be to have libusb early on
the link line; as libraries are guaranteed to be searched from left 
to right. basically it's what the LD_PRELOAD trick does, but at run
time.

It would imply modifying the link of digikam, but also of showfoto
and may be other binaries I am not aware of.

I have the same problem using digikam 2.0 beta5 on openSUSE with the packages in http://download.opensuse.org/repositories/KDE:/Unstable:/Playground/openSUSE_11.4/

Downgraded to 1.9 as supplied in KDE core and it works.

To Philip #19 : Mandriva crash too when i try to open my Samsung phone by PTP Gphoto driver. Same backtrace.

Gilles Caulier

To Pierre #20 : Perhaps we can solve this issue to fix the linking parts from OpenCV used in libkface.

The openCV part which use libdc1394 is not used in libkface. Currently, if i understand fine libkface OpenCV linking rules, all OpenCV parts are linked with libkface.

This can be a solution to limit to wanted openCV parts in libkface linking rules ?

Gilles Caulier

I can reproduce now the problem on my computer. It very simple to reproduce, outside cameragui: Go to digiKam setup, camera section and try to add a new camera manually, or to perform an auto detection.

I make investiguations around libkface/openCV linking. Currently libkface is linked to OpenCV using CV, CVCORE, CVAUX, and HIGHGUI components. It can be linked using only CVAUX alone.

Compilation is under progress. I will see if this will remove libdc1394 depency to libkface and prevent crash with gphoto2.

Gilles Caulier

Same problem if libkface is linked only with CVAUX opencv component :

This is an indeep incompatibility between opencv and libgphoto2, through libdc1394. This cannot be fixed into digiKam or libkface (excepted if i import only relevant opencv code myself in libkface, which i will never do of course)

This problem must be _URGENTLY_ reported to libdc1394 and opencv (and perhaps gphoto2) projects to find the right solution.

Gilles Caulier

@Pierre #20 :

How to specify in cmake to preload libusb on the right way for digiKam, using LD_PRELOAD ?

Gilles Caulier

To Philip, #19 : I can confirm that if i compile myself opencv with libdc1394 support, Gphoto2 do not crash into digiKam.

My system is Mandriva 2012.0

Gilles Caulier

Nicolas,

If it's possible, make OpenCV for Mandriva without libdc1394 support, until we found a better way to fix this problem. There is just an option to turn off in cmake configuration...

i would like to help but does not know cmake.
i will have a look but do not expect too much on my side
sorry

a quick and dirty solution is to modify   core/digikam/CMakeLists.txt

if you add explicitly libusb in the list of libs in libdigikamcore you solve the problem
for all programs using it (digikam and showfoto)

around line 72

ADD_DEPENDENCIES(digikamcore digikam-gitversion)

TARGET_LINK_LIBRARIES(digikamcore
        /usr/lib/libusb.so
        ${QT_QT3SUPPORT_LIBRARY}
        ${QT_QTSQL_LIBRARY}

        ${KDE4_KDECORE_LIBS}
 
works on Ubuntu 11.04

At least modification is in the right file I think...

Pierre,

Thanks for the informations. I will test on my computer and use the right cmake way to link digiKam & co with libusb.

I cannot reproduce the crash here, under Linux and MACOSX. Take a care to make a fresh checkout of source code without any compilation cache.

Gilles Caulier

Thanks for all your help Gilles..

Do you see any reason I should suspect packages outside of digikam? should i recompile gphoto2 or anything else??

I recompiled, but still getting this error.. I also see this in the console output.. i'll try recompiling gstreamer as well..

GreyBones,

I don't recompile OpenCV and Gphoto2 to kill this crash. I just apply my previous patch, used offical OpenCV and Gphoto2 from Mandriva repository (OpenCV compiled with libdc1394 support), and now digiKam do not crash when Gphoto2 API is called.

Note : at startup, i can see that digiKam try to init libdc1394 now, which prevent conflict between OpenCV and Gphoto2 :

... look the first line at startup. You must see the same. My patch just link digiKam with libusb when Gphoto2 support is enabled. OpenCV is always used with digiKam 2.0.0, for face detection support (it's not optional)

*** Bug 279458 has been marked as a duplicate of this bug. ***

Is there a fix for this on the way? I will report to archlinux packagers, maybe they can disable libdc1394 support in OpenCV.

for now, downloading in cli with gphoto2 does not exacely feel professional ;)

Uhm, what is required to make this work? This is marked as fixed, but where lies the fix?

The most current git is supposed to be fixed, but mine still crashed
too.. I think it's an opencv and 1394 issue, but no release of either
I have tried seems to resolve the issue..

fix is in the link commands where the order of the libraries has been modified to garantee than libusb is linked before libdc1394.

This should avoid that the function usb_init from libusb si called instead of the one from libdc1394.

please use ldd command on the binary to see if this is really the case.

if libusb is before libdc1394 there is an other problem.

if it is after, this problem should be solved first

*** Bug 279111 has been marked as a duplicate of this bug. ***

As can be seen below, the linking order seems to be the problem.

I will make the archlinux digikam packager aware of this bug, is there anything more I can do?

To solve this issue on my computer in the past, i forced libusb to be initialized at startup of digiKam. Yes, linking order is important here.

When you start digiKam from a console, do you see this line :

Do you have a dc1394 device on your computer. I don't have one, and digiKam do not crash.

Someby in this room who can reproduce the crash due to uncompatibility between gphoto2 and openCV can check if my last commit (see #59) fix the problem ?

I cannot reproduce since a long time now this crash. So i cannot hack better...

Thanks in advance

Gilles, Robert,
I'll backport the commit to Gentoo digikam-2.0.0 tonight. We'll hopefully see then...

It still crashes on gphoto init, and LD_PRELOAD still fixes it.

Even moving the libusb linking command to be the first link command that cmake 
sees does not seem to help.  Poking at it a bit, the highgui library from 
opencv links to libraw1394 and libusb, in that order. 

I tried to prevent linking to highgui, but libface uses it.

I also tried linking libusb in to kface and redeye_plugin before they link to 
opencv, but it does not seem to make any difference.

I suspect what is going on is that because libusb is already linked into 
highgui.so, even though libusb is on the list, it doesn't get re-linked. 

If I have time tomorrow I am going to compile opencv and change the link order 
there.

Hello,

You can check where usb_init() comes from by setting this environment variable :
LD_DEBUG=bindings

is it possible to change the resolution state to REOPEN ?
This issue is not fixed ...

If you read the story, you will see that i have been able to reproduce the problem on my Mageia Linux computer. I FIXED that.

Now, i cannot reproduce it.

The question why the problem still exist with some other distro...

Here are the relevant lines with and with out LD_PRELOAD

with (works properly):

sorry if this shows up twice

This is on Ubuntu oneiric (development branch)

Somebody has already fixed this issue which comes from libdc1394 :
http://sourceforge.net/tracker/?func=detail&atid=308157&aid=3361405&group_id=8157

I applied the attached patch, then recompiled libdc1394.
The proposed patch definitively fixes the crash :)

So, it's an UPSTREAM fix...

I still have this problem in Version 2.2.0 on openSUSE 12.1
Using KDE Development Platform 4.7.2 (4.7.2) "release 5". In what version of digikam is it fixed.

I have found on openSUSE 12.1 that the crash only occurs when there are pictures on the camera opened in ptp mode. If the pictures are all deleted, the camera opens without a crash to show an empty directory.

It's normal. PTP mode use Gphoto2 drivers, which play with libdc1394, as OpenCV do. This is why it crash...

Gilles Caulier

Does this mean there is no fixed version of digiKam yet for ptp import. 
Using Gwenview works reasonably well.

I think what he meant is that the problem isn't in Digikam itself but in libdc1394 especially in combination with OpenCV that conflict how they initiate the USB connection. There is a patch for libdc1394 that fix this problem but I don't know how many dists that use the patch as the problem isn't that common in programs or use OpenCV in this way.

If you can reproduce the crash with openSUSE could you please open a bug at bugzilla.novell.com and refer to this bug and http://sourceforge.net/tracker/?func=detail&atid=308157&aid=3361405&group_id=8157 in order to get an updated libdc1394.

According to https://build.opensuse.org/package/view_file?file=libdc1394-visibility.patch&package=libdc1394&project=openSUSE%3A12.1&rev=b46f15167efa14dffde3074a9c5abdc1 the patch is already in libdc, so it must be something different.

I have just installed openSUSE 12.1 on another machine. I can access the images via ptp on my camera on the new machine but not the old. Both machines just updated with software update.
-rwxr-xr-x 1 root root 213856 Oct 30 16:32 /usr/lib64/libdc1394.so.22.1.5
digikam-2.2.0-3.3.2.x86_64
same on both machines. Different motherboards, all other hardware the same.

apt-get install digikam works fine for install digikam but it will not
update the kdelibs automatically as needed. The problem lies in that
some kdelib package is not updated.

What does "apt-get update && apt-get upgrade" say?

The important packages to check are libkipi8, libkdcraw20 and
libkexiv2-10 they should all (at the moment of writing this) have
package versionname as follow: 4:4.7.2-oneiric~ppa2

Check those and see if you find what is missing.

Sorry, there are differences in version names

libkipi8 = 4:4.7.4-oneiric~ppa2
libkexiv2-10 = 4:4.7.2-oneiric~ppa2
libkdcraw20 = 4:4.7.2-oneiric~ppa2

That is what you should have installed right now

Sorry, disregard from post #93 and #94. I answered in the wrong thread for the wrong post via the mailinglist. The answers have nothing to do with this problem. Don't know how to delete the postings here.

Sorry about that.
