Package: digikam
Version: 4:4.3.0-1
Severity: important

Hello,

Digikam has stopped working today, it did work yesterday, and I did an
upgrade of digikam:amd64 (4.1.0-1+b2, 4.3.0-1) in between. So, even if
the segmentation fault is in libexiv2, I suspect the issue with digikam.

Anyway, feel free to re-assign or ask for more information, here the bug
description...

Digikam starts first, to the point where the hint dialog shows up, then
it crashes.

When starting it from the gdb, I get the following output (I don't get
more when starting digikam normally):

(gdb) run

I tried to reproduce the issue using 'exiv2 -f -l /srv/photos/tmp -v
-ep' but didn't identify anything suspect. This said there are many
images and I can't promise I didn't oversee something. It would be nice
if it would be possible to make digikam spit out where it encounters a
problem.

Let me know what I can do to help solve this issue, I can't currently
use digikam at all and manage my pictures.

Thanks, Eric
