Sentry Crash Report:

Description Friedrich W. H. Kossebau 2016-02-07 13:49:14 UTC 
Application: plasmashell (5.5.3)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-3-default x86_64
Distribution: "openSUSE Tumbleweed (20160205) (x86_64)"

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

Multiple virtual desktops, A & B.
Firefox window shown on A.
Konqueror window shown on B.

Looking at a website in Konqueror.
RMB click on a link, "Open with..." > "Firefox".
Results in new tab in Firefox window on A and automated switch to A (by KWin or Plasma?).
While page in tab is loading, I switched instantly back to B.
-> crash

I remember to have seen this behaviour since I first switched to Plasma5, which was perhaps around 5.2.

The crash can be reproduced sometimes.

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