Description Dan Mossor 2015-02-23 01:37:13 UTC 
Application: plasmashell ()

Qt Version: 5.4.0
Operating System: Linux 3.18.6-200.fc21.x86_64 x86_64
Distribution: "Fedora release 21 (Twenty One)"

-- Information about the crash:
I woke my laptop up from sleep, and left it charging for a while. I went to open the system tray to check the battery level, but when I clicked on the arrow to show the hidden icons, plasmashell crashed. The system automatically restarted plasmashell, and the system tray returned to normal operation.

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