Application: plasmashell (5.4.2)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-19-lowlatency x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:
I was doing nothing special
- Unusual behavior I noticed:
I guess the time was changing end a redraw was occuring on the clock applet (digital version)

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