Application: plasmashell (5.3.2)

Qt Version: 5.4.2
Operating System: Linux 4.1.0-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

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

I was looking for an application to change the size of the desktop to adapt it to the window size offered by VirtualBox. KDE just started, nothing in particular was done or changed to the defaults as shipping in Debian Experimental.

- Unusual behavior I noticed:

The KDE bar was not visible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Floating point exception
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
