--- Comment #1 from Matthias Andree <matthias.andree at gmx.de> ---
I haven't found an image path printed in .xsession-errors nor on the console.

If there is a way to run digikam with extended debugging information, please
point me to the instructions.

While trying to reproduce, I got this in the console:

KCrash: Application 'digikam' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit

*static_d()' after destruction. Defined at
/home/mandree/VCS-other/digikam.git/core/libs/threadimageio/filereadwritelock.cpp:385


And retrying the same with strace -feopen -p $(pidof digikam) reveals the
following near SIGSEGV. 

Apparently this happens when I am opening the preview for an .AVI image that
was filmed with my Fuji F200EXR - and I need only select the album to trigger
the crash:

[pid  9514] open("/foto-backup/Bilder/Zillertal-2012-03/DSCF3028.AVI",
O_RDONLY) = 39

Maybe related:

$ LC_ALL=C exiv2 /foto-backup/Bilder/Zillertal-2012-03/DSCF3028.AVI
Exiv2 exception in print action for file
/foto-backup/Bilder/Zillertal-2012-03/DSCF3028.AVI:
/foto-backup/Bilder/Zillertal-2012-03/DSCF3028.AVI: The file contains data of
an unknown image type


Any further instructions for debugging this?
