Description Mathieu Carpentier 2016-01-28 07:41:55 UTC

Application: krunner (5.5.3)

Qt Version: 5.5.1
Operating System: Linux 4.2.8-200.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:
After I logged to my system, I used Alt+F2 to launch krunner. I could type what I was looking for, but before I could launch the desired application, krunner crashed. Immediately after I could use krunner with the same keyboard shortcut and same search without problems.

The crash can be reproduced sometimes.

-- Backtrace:
Application: krunner (krunner), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
