Application: digikam (2.5.0) KDE Platform Version: 4.8.4 (4.8.4) Qt Version: 4.8.1 Operating System: Linux 3.2.0-27-generic x86_64 Distribution: Ubuntu 12.04 LTS -- Information about the crash: - What I was doing when the application crashed: I started using digikam this morning, imported some photos from 2 memory cards, added keywords and geographical information, used merging of bracketed images (HDR) and tried to explore digikam a bit. Nothing unusual, I suppose. - Unusual behavior I noticed: In some situations digikam needed a long time to finish some internal operations, which causes the window to be greyed out many seconds. The same happened at last, so I locked the screen and when I came back aufter some minutes, I saw the crash message after unlocking the account. - Additional information: Currently there are 802 files (jpg, png, xmp) with 1.8 GB in digikam's folder. -- Backtrace: Application: digiKam (digikam), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Sound like it crash in Color Management. Do you assigned a color profile for your screen ? Which icc profile file ? Also it crash internally in Qt screen management ? It sound like a problem with Qt or your X11 video driver. Please investiguate... Gilles Caulier
I did not change any color management settings, nor did I assign a particular color profile.
Well, sound like a binary compatibility issue in your system with Qt or X11. Also try to use last stable digiKam 2.7.0. Gilles Caulier
Code (crash in second line): QDesktopWidget* desktop = QApplication::desktop(); int screenNumber = desktop->screenNumber(widget); We dont check the desktop widget, and from the docs the state of a null desktop widget is not defined/expected, but the crash comes from accessing this. I will add a null pointer check. If there's not a null pointer and still crashes, it's an upstream problem.
