Description Oliver Freyermuth 2018-07-29 13:04:29 UTC 
Application: plasmashell (5.12.5)
 (Compiled from sources)
Qt Version: 5.9.6
Frameworks Version: 5.46.0
Operating System: Linux 4.17.2-gentoo x86_64
Distribution: "NAME=Gentoo"

-- Information about the crash:
- Custom settings of the application:

VLAN connection created for eth0 with method=auto. 
This is a laptop, the VLAN is not available every time I boot. 
If I am at a place where it is not available, VLAN stays activating and never finishes - but segfaults, pulling plasmashell with it. 

Only workaround: 
nmcli con down <connectionname>
Then Network Manager applets stops segfaulting. 

In a previous version of network manager / qt it was working. Sadly, I don't know which version exactly.

The crash can be reproduced every time.

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