Application: plasmashell (5.4.3)

Qt Version: 5.5.1
Operating System: Linux 4.3.3-2-default x86_64
Distribution: "openSUSE Tumbleweed (20151229) (x86_64)"

-- Information about the crash:
The crash appears to be a direct result of the KDE Wallet request for its password from the initial switching off of the VPN connection.

1. After disabling the VPN connection, KDE Wallet pops up and requests the password.
2. Connection to a new VPN is initiated which results in a momentary crash of Plasma 5. 3. Connection is however, successfully established after automated restart of Plasma 5.
4. Subsequent request for switching VPN servers are establiushed without issue.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
