Bug 255010

Application: digikam (1.2.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-25-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
It happened to me many times now that when I undo some edition operation in the digikam editor, the picture fails to show up again, and the next action I take results in a seg fault. I am editing a DNG file. Running Ubuntu 10.04, after dist-upgrading from 9.10.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
