The trace is uncomplete. Please run digiKam through gdb and post backtrace here.

i recommend to test digiKam 1.5.0 too...

Comment 2 Jens Berthold 2010-11-03 14:14:54 UTC
Again with 1.4.0, I did a thumbnail creation scan, this time using gdb to start digiKam.
The crash seems different this time (?)...

Last output in gdb before the crash:

==> it's very similar than file :

https://bugs.kde.org/show_bug.cgi?id=255852

Look comment #1 about pure virtual method.

Marcel manage this entry. I'm not sure if this one is a duplicate, but i recommend to follow #255852 and check if it solve this file.
