Description sebastien.f 2006-01-14 17:47:55 UTC 
Version:            (using KDE KDE 3.5.0)
Installed from:    Compiled From Sources
Compiler:          g++ 4.0.2 ubuntu 
OS:                Linux

kopete crash when going to Setting->Configure.
Kopete is not logged when crashing.

I compile the SVN version : Checked out revision 498049. (dev-0.12)
(I have the same thing with the ubuntu package kopete 0.11)

This cash does not appens all the time. But very often. 8/10.
This is due to webcam because when I unplug this it works.

This what kopete give to me in the konsole:

Comment 1 Matt Rogers 2006-01-14 18:33:18 UTC 
please provide a backtrace. (copy the output from the backtrace tab of the kde crash handler, and add it as a comment to the bug report)
Comment 2 sebastien.f 2006-01-15 22:20:40 UTC 
This is the backtrace. Seems not to be usefull because there are no symbol.
This is strange because I compile kopete svn with --enable-debug=yes ?

(no debugging symbols found)
Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".

Stacktrace is corrupted, try to run kopete under valgrind.

Comment 4 sebastien.f 2006-01-16 00:43:20 UTC 
Why not. just tell me in 3 lines how to use valgrind and what do you want ?
Comment 5 Matt Rogers 2006-01-31 01:51:08 UTC 
can you provide any info on your webcam drivers? name and version number would be helpful since certain versions of certain drivers cause kopete to crash.

Comment 12 Juuso Alasuutari 2006-04-15 03:29:56 UTC 
I forgot to say: I do _not_ have a webcam or any other video device, if one doesn't count Nvidia Geforce Go 6800 as such. The crash happens every time when I click the "Devices" icon in Settings -> Configure.
Comment 13 Juuso Alasuutari 2006-04-15 03:37:26 UTC 
A frend also experiences this same crash when clicking on the "Devices" icon. I'll post his backtrace here. Some info: kernel 2.6.16-rt14, Xorg 7, QT 3.3.6, KDE 3.5.2, video card ATI Radeon 9800 XT and open source Radeon driver from mesalib.

Reproduced on Fedora Core 5, KDE 3.5.2, Kopete 0.11.1.  No webcam here either.  I deleted my $KDEHOME/share/apps/kopete and $KDEHOME/share/config/kopeterc files, and the error persists.  Backtrace:

Same here, on gentoo. 
I post my backtrace, bacause it has line numbers, otherwise it seems the same as the others :) I have no webcam either. 
This bug is very annoying, since it won't let me change any Kopete setting, not only those regarting webcams! For me it happens any time I click on Settings -> Configure...

Using host libthread_db library "/lib/libthread_db.so.1".

Comment 22 Philip Rodrigues 2006-04-21 15:47:47 UTC 
Created attachment 15719 [details]
patch to fix

The attached patch seems to fix the problem. If you have the kopete sources,
please apply this patch in libkopete/avdevice and recompile. I made it against
0.12-branch, but it seems to apply against 0.11 too.

Analysis: Available video devices are stored in a QValueVector. Bounds-checking
wasn't done in the (get|set)Brightness etc methods, hence the crashes. The
patch does the bounds-checking and returns a default value if there are no
video devices (or rather, if the requested video device doesn't exist). A
better solution to the problem would be to have a completely different code
path if no video devices are found (eg, don't show the "devices" GUI page, or
something). Anyway, I guess the bounds checking should be done anyway, since it
prevents crashes, with the worst-case then being brightness/contrast/whatever
getting set incorrectly.
Comment 23 Philip Rodrigues 2006-04-21 16:01:56 UTC 
Oh, and it looks like there might be two related, but slightly different crashes in this bug report: the backtrace in comment #9 looks different to the others, and I don't think my patch will fix it.
Comment 24 Jussi Kekkonen 2006-04-22 00:23:45 UTC 
Oh yes, crash happens, if there's no webcam plugged and trying to tiggle those controls. Philip's patch does fix this, any webcam specialists find any objections to apply this ?

Comment 33 Philip Rodrigues 2006-04-27 13:39:48 UTC 
You need the source code. You're probably best off waiting until 0.12 is released if you're not already familiar with compiling KDE apps, but if you really want to, you can find instructions at:

I can't compile the source-code. Refer to KDE-Forum: http://www.kde-forum.org/thread.php?threadid=14645

Also, I think the Kopete developers should release a 0.11.1 since not everyone who are technically knowledgable like us knows about http://bugs.kde.org or knows how to patch things.
Comment 38 Bartosz Fabianowski 2006-04-29 21:55:39 UTC 
There is no need for a 0.11.1 release - 0.12 is just around the corner and will have the fix for this bug in it.

Your config.log says "g++: command not found". Are you sure that gcc-c++ is installed? This is the name of the rpm package with SL 9.2, try "pin g++" in a konsole to find out wether it is installed and what its name is respectively.
Comment 40 Cláudio da Silveira Pinheiro 2006-04-30 02:06:38 UTC 
I'd like to point that the fix was backported to kopete stable (0.11.x) and ported to kde4 too, days ago. All bugfixes to video support are ported down and upstream.
Distros must update kde/kopete packages themselves, and lots of them already do it. Providing updated official packages for a myriad of distros is beyond our reach as developers.
Anyway Kopete 0.12 is far better overall than 0.11.x, and if you want your distro to support it you must get in contact with their support line to ask for it. We as developers do not have the power force a distro to release a new version at our will (even developers who currently work for a distro may not be able to do so).
If you want to test it by yourself most developers (including me) are willing and able to help you. We can be reached in irc, server irc.kde.org (affiliated to freenode) in channel #kopete . To be able to compile it by yourself some things are required, like a C++ compiler and other libraries' headers (-dev or -devel packages) kopete depends of. Without it is virtually impossible to compile kopete.

Comment 44 mi+kde 2006-05-12 16:48:12 UTC 
That's an ugly patch, if I may... Can't the check for the current_device's validity be moved into a single location somewhere, instead of repeating it in each method?

Generally, I think, it is wrong to have a function validate its environment and arguments every time. If something is not right, the function should not be callable in the first place.

A function may only validate things, that only the function knows about (like whether the requested gamma makes sense). But the check for whether or not the camera *exists* can and should be done prior to calling these function...
Comment 45 Cláudio da Silveira Pinheiro 2006-05-12 17:52:55 UTC 
Let me disagree with you.
By design the VideoDevice and VideoDevicePool APIs have a clear intent to _never_ crash, even if by mistake methods are called in a different order than intended and/or with absurd parameters. Please understand we're accessing _hardware_ and issuing kernel calls, and that the video device is supposed to be accessed concurrently. and doing try/catch exceptions it even uglier and error prone than simply checking if a given QValueVector has elements. I would be glad to discuss a better design pattern that meet the requisites and is cleaner that the present one.
Take in account that the present code is a work-in-progress, so some things are still settling and some proper thread-safe checks are still missing. If you feel you can contribute please don't hesitate about contancting me so we can coordinate our efforts.

Oops, I thought I'd searched hard enough but not found this one before filing #128300. Thanks, Bartosz, for setting it straight.

I've also attached my own patch here. Unlike the first patch attached here, mine simply avoids calling those methods unless there is a current device. Closer to what mi+kde commented above. This is the first patch I've submitted to any open source project, let alone KDE. Please let me know what you guys think.

Another patch

This fixes the bug that has kopete crash when selecting Settings -> Configure.
The initialiation code was missing a call to "scanDevices()," which was present
in earlier versions of kopete. I added it back in, plus I made sure the call to
setVideoInputParameter() would only be called when a device was present.

Reopening due to bug 138812. It looks like we needs the bounds-checking in videodevice::setbrightness, and a few other places, too.
Comment 57 John Langham 2007-03-04 13:18:40 UTC 
Same as http://bugs.kde.org/show_bug.cgi?id=138812 
Same webcam Logitech QC Pro 5000

UVC cams require additional code to decode mjpeg, which is currently being worked upon.

The SVN branch is branches/work/kopete/avdevice_overhaul, for the adventurous.
Comment 60 German de la Cruz 2007-07-30 17:27:04 UTC 
what about the uvc webcams?
Comment 61 Cláudio da Silveira Pinheiro 2007-08-03 20:37:33 UTC 
I'm coding it. Expect it to work next week.
Comment 62 Alex Lowe 2007-08-11 00:59:03 UTC 
I move to close this bug, as it hasn't existed (for me at least) since KDE 3.5.4.
Comment 63 Cláudio da Silveira Pinheiro 2007-08-11 01:34:58 UTC 
The bug is real, repeatable with UVC devices. There's a pach in the comunip branch that fixes it, I just didn't commit it to -stable yet cause I'm doing some serious rework to the controls' code.
Comment 64 Cláudio da Silveira Pinheiro 2007-08-12 13:47:02 UTC 
The control's code is done, colorspaces fixed, and tested, not a single crash even after stress-testing it with 5 capture devices (comunip branch).
I'll close this bug after I get confirmation from two more testers (who were already contacted).
Comment 65 Cláudio da Silveira Pinheiro 2007-08-13 12:29:27 UTC 
Fixed in the comunip branch.
