Description Guenther M. Erhard 2010-02-21 18:10:16 UTC 
Version:            (using KDE 4.3.5)
OS:                Linux
Installed from:    Ubuntu Packages

Hi,

I had two jpg pictures loaded in digikams lighttable. I deleted the one I did not like and switched back to the digikam main window (lighttable was still open, also digikams editor). Then digikam crashed and gave me following crash report. The crash is not always reproducable, but it happened already several times.

I use digikam Version 1.2.0 rev.: 1093437 with KDE 4.3.5 on Ubuntu 9.10. compiled yesterday without warnings.

Application: digiKam (digikam), signal: Segmentation fault
