Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.1.34-33-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
Occasionally, when initialising a PPTP connection via NetworkManager, Plasma crashes. The VPN connection still will be established and NM shows this connection running when restarting Plasma.

System:
* openSUSE Leap 42.1 with Plasma 5 (official repo)

Packages:
* plasma-framework 5.21.0-15.1
* plasma-nm5 5.5.5-9.1
* plasma5-workspace 5.5.5.2-12.1

The crash can be reproduced sometimes.

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