Description kdebug 2015-08-03 21:25:37 UTC 
Application: plasmashell (5.3.2)

Qt Version: 5.5.0
Operating System: Linux 4.1.3-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

I'm running KDE on an vncserver (arch linux tigervnc 1.5.0-1), everytime I  switch vncviewer (also arch linux tigervnc 1.5.0-1) to fullscreen plasmashell crashes.

~/.vnc/xstartup lookes like this:

#!/bin/sh
ssh-agent startkde &
exit 0

vncserver is started at boot time like this:

su - myuser -c "PATH=/home/ml/bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl vncserver -geometry 1920x1080 :1 -listen tcp -SecurityTypes TLSVnc"

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
