Sentry Crash Report:

Description Roy 2017-03-27 08:17:50 UTC
Application: plasmashell (5.5.5)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.4.0-66-generic x86_64
Distribution: Ubuntu 16.04.2 LTS

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

- Unusual behavior I noticed:
The Entire Plasma Desktop would crash when I tried to chain,or use,more than three concurrent VPN at a time

- Custom settings of the application:
OpenVPN services was used (This probably is irrelevent,but I will include it anyway,)

The crash can be reproduced every time.

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