Thanks for the bug report. The crash happens in Nepomuk code, so I'll reassign. I'm not really sure where to look for the bug though. It looks like there is some memory corruption, which can in principle come from anywhere, but maybe Vishesh has an idea. Can you reproduce this crash? If yes, can you try to run Dolphin in Valgrind: valgrind dolphin 2> log.txt (note that this will make Dolphin very slow), then reproduce the crash, and attach log.txt here? Thanks for your help. Are you sure you were just transferring data? This crash is produced by some file getting selected and either the information panel getting populated or the tooltip being shown. Anway, it still should not crash. The valgrind data would be quite helpful. I'm not sure why it's crashing, the code looks fine to me.

It's the information panel, according to the backtrace. *** Bug 325445 has been marked as a duplicate of this bug. *** *** Bug 322259 has been marked as a duplicate of this bug. *** Application: dolphin (4.11.2) KDE Platform Version: 4.11.2 Qt Version: 4.8.2 Operating System: Linux 3.11.6-031106-generic x86_64 Distribution: Ubuntu 12.04.3 LTS -- Information about the crash: Open Dolphin , trash any file.
