Description v.vogelhuber 2013-10-24 14:44:23 UTC

Application: dolphin (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:

Moved mouse after clicking on a directory tree item. I couldn't reproduce it, so it might not be directly related to the mouse input

The crash does not seem to be reproducible.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 1 Frank Reininghaus 2013-10-24 19:37:09 UTC

Thanks for the bug report! There have been some changes recently to make the relevant code more robust, see https://git.reviewboard.kde.org/r/113070/.

I think that this kind of crash will probably not happen any more in Dolphin 4.12. If you see a crash with this backtrace again in Dolphin 4.12 when it's out, please let us know.
