Comment 2 caulier.gilles 2013-02-06 19:26:25 UTC 
There is nothing suitable in your trace. I suspect a binary compatibility issue with libkdcraw...

run Showfoto in gdb to get a better backtrace : http://www.digikam.org/contrib

Comment 5 caulier.gilles 2013-02-06 22:04:40 UTC 
2 Solutions :

It's a libraw or Exiv2 crash. Both libs are used by Showfoto.

If you are able to identify which NEF files crash the application, please try to share file over internet to try to reproduce here the problem.

Also, go to Help/Components Info dialog and copy and paste here contents

New crash information added by DrKonqi

showfoto (2.9.0) on KDE Platform 4.9.00 using Qt 4.8.1

- What I was doing when the application crashed:

I told showFoto to show thumbnails for the directory containing the file 803.NEF.  ShowFoto crashed when it started rendering the thumbnail for this image.

I cannot do that, you would have to scratch your CD where the file is.

Here is what file says:
803.NEF: ERROR: cannot read `803.NEF' (Input/output error)

There is no way I can upload a file that cannot be read.

Comment 8 Christopher Yeleighton 2013-02-07 00:36:43 UTC 
It should be noted that in this particular case the offending files are all right; they were reported unreadable because of KDE’s fault.  I killed KDE (it would not log out) and mounted the CD from console and read them with no problem.  I wonder how KDE manages to confuse the kernel that much.

Comment 10 Marcel Wiesweg 2013-02-07 18:56:42 UTC 
Christopher, do I understand your gdb logs correctly:
The exception which is rethrown has been identified as one from libexiv2?

My media does not lock my computer, where did you get that?

Observe that:

1.  libexiv throws by design (see above).
2.  Throwing under Qt in the context where libexif throws is unsupported and violates the contract (see above).
3. In an environment where throwing is unsupported (like e.g. in a C API internally implemented in C++), any potential throws should be caught and translated to a failure that the calling environment supports.
4. ShowFoto fails to protect Qt from libexif as it should.
5. Crashing in presence of a persistent storage failure is a bug.  Compare the file utility; it does not crash and neither should ShowFoto.  

The bottom line is, scratches happen, crashes should not.

New crash information added by DrKonqi

showfoto (2.9.0) on KDE Platform 4.9.00 using Qt 4.8.1

- What I was doing when the application crashed:

I told showfoto to open a NEF file.  Showfoto asked me to choose the file.  I used the chooser to browse the thumbnails.  All the images were NEF, showfoto crashed trying to display one of them.

Comment 13 Marcel Wiesweg 2013-02-09 18:20:54 UTC 
Of course, we catch libexiv2 exceptions whereever they can be thrown.
I suspect a binary compatibility problem where the C++ symbols of exiv2's exception classes are not recognized properly by the catching library.
Comment 14 caulier.gilles 2013-03-18 09:15:08 UTC 
As we suspect a Binary Compatibility issue, please update to last 3.1.0 and try again.

New digiKam 4.11.0 is available :

https://www.digikam.org/node/740

Can you reproduce the problem with this release ?
Comment 16 caulier.gilles 2015-08-23 14:33:15 UTC 
digiKam 4.12.0 is out :

https://www.digikam.org/node/741

We need a fresh feedback using this release please...
Thanks in advance.
Comment 17 caulier.gilles 2016-07-15 20:46:11 UTC 
With digiKam 5.0.0, this problem is not reproducible.
I close this file now. Don't hesitate to re-open if necessary.
