Application: plasmashell (5.3.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-25-lowlatency x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
i was not doing anything. I was out and when i returned I saw the plasma crashed window an screen
- Unusual behavior I noticed:
nothing
- Custom settings of the application:
I have the fuzzy clock widget active which changes regularly the string showed for clock value and rearrange the task bar width regularly - might be a trigger ?

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