Description Reuven 2015-10-07 23:31:45 UTC

Application: plasmashell (5.4.1)

Qt Version: 5.5.0
Operating System: Linux 4.1.8-200.fc22.i686 i686
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:
Each time when I  
 - begin to type in the "Search" row in main menu (to make a search) or
 - begin to type in the "Run Command" row from " right-clicked" desktop menu
After crush it generally succesfully restarts to initial state. But sometimes (after 2-3 incidents) the screen may stay black with only mouse cursor on it. 
Ctrl-Alt-Del helps to get to Logout dialog which helps to restart Plasma

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

This is crashing in your graphic driver which we can't do much about.

Please upgrade/downgrade your version of mesa. See information (including a workaround) in the linked report
