Attachments: Valgrind logfile taken up to Digikam crashes with segmentation fault

Description Heinrich 2010-11-01 15:54:45 UTC 
Application that crashed: digikam
Version of the application: 0.10.0
KDE Version: 4.3.5 (KDE 4.3.5) "release 0"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.14-0.4-desktop i686
Distribution: "openSUSE 11.2 (i586)"

What I was doing when the application crashed:
Using 
digikam 1.10.0
KDE 4.3.5 "Release 0"
OpenSuSe 11.2
Kernel 2.6.31.14-0.4-desktop #1 SMP PREEMPT

I did some work with photographs (re-sizing, rotating, changing colors, etc.).
After I did this for 3-5 files, the program crashed. This is (besides the number of files needed) reproducable.  
I created a Valgrind log of one of the crashes, in the hope that this helps (that one did need patience!)

Regards, Heinrich

Since digiKam 5.0.0, KDirWatch was been replaced by QFileSytemWatcher. It will
not reproducible.
