Description Thomas Pasch 2015-10-30 16:20:42 UTC 
Application: plasmashell (5.4.2)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-16-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:
* directly after 'sudo service NetworkManager restart' the Window Bar crashed

- Unusual behavior I noticed:
* Window Bar of Kubuntu wily behaves strange: After login, it takes about 1 minute for the Icon to appear in the bar (but the bar itself is there immediately

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

This is crashing in your graphic driver which we can't do much about.

Please upgrade/downgrade your version of mesa. See information (including a workaround) in the linked report.
