Bug#790825: (no subject)

[Julien Goodwin <jgoodwin@studio442.com.au>]

This bug also appears to be why konsole (and only konsole) is crashing 
for me which I had reported as bug 795815.

The test program Sebastian provides also causes the problem on my system 
(Lenovo T430, AMD64, systemd, in an XFCE session).

Sadly the upstream bug simply says "please try with 5.5" which looks to 
be winding its way through unstable.
