Description boblovgren55 2014-11-09 15:40:56 UTC 
Application: plasma-desktop (4.11.12)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.6-2-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

I had three Konsole windows minimized which were all grouped. When clicking on the group, plasma completey crashed. I was able to reproduce the bug over and over again, after restarting plasma-desktop from the console. This type of bug is not acceptable for any type of production system or workstation and needs fixing ASAP.

- Unusual behavior I noticed:

Sometimes when selecting folders on the desktop, plasma totally crashes. Again, unacceptable.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Bus error
Using host libthread_db library "/lib64/libthread_db.so.1".
