Description lpmccracken 2016-04-15 16:59:58 UTC 
Application: plasmashell (5.4.3)

Qt Version: 5.5.1
Operating System: Linux 4.5.0-0.slh.1-aptosid-amd64 x86_64
Distribution (Platform): Debian stable

-- Information about the crash:
- What I was doing when the application crashed:
I clicked the Launcher on the left side of the panel, typed the first few letters of chromium, maybe four or five letters, pressed enter, then the plasma shell crashed.  The panel with the Launcher & the system tray went away.  The Crash reported started, Chromium started, & after 10 to 20 seconds, the panel came back.

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