Comment 1 Marco Martin 2015-05-20 15:22:44 UTC 
the backtrace seems incomplete, plasma-workspace debug packages missing?
Comment 2 Kaisar Arkhan 2015-05-20 22:34:49 UTC 
What are the debug packages exactly? I only installed gdb.
Comment 3 Kaisar Arkhan 2015-05-20 22:52:50 UTC 
Created attachment 92750 [details]
plasmashell Backtrace

Nevermind , all of them are here but the crash reporter says it doesn't exist (http://a.pomf.se/eemqsm.png)
