Description milan zimmermann 2015-05-25 22:01:27 UTC 
Application: plasmashell (5.3.0)

Qt Version: 5.4.1
Operating System: Linux 4.0.3-1-desktop x86_64
Distribution: "openSUSE 20150522 (Tumbleweed) (x86_64)"

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

I had 2 Firefox windows, first with several tabs, another with a single tab. I dragged the single-tab (from the window with only one tab) to "join" the tab list on the first window. As the (now empty) window disappeared, Plasma crashed.

It seems always duplicable.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
