Description David 2015-05-13 12:21:10 UTC
Application: ksysguard (5.3.0)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-17-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
sometimes plasma 5 crashes without reason - it happened ... 
it didnt relaunch itself so i started a new instance in konsole $(plasmashell &) and
the old plasmashell process still showed up eating 7gigs of memory but was in disk sleep
.. i wanted so see detailed mem info but there was no text so i closed the (ctrl+esc) task manager and it crashed
- Unusual behavior I noticed:
plasmashell crashed and didnt restart itself and ate up 6.8 gigs regarding to ksysguard (started in "minimal mode" via ctrl+esc

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