Bug 372400

Summary: Plasma shell aborts - apparently some sort of timeout - every time I try to log in since system updated.

Sentry Crash Report:

Description neuschein-cotton 2016-11-12 20:53:34 UTC 
Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-47-generic i686
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Trying to log in.
The crash is reported 3 times. If I then leave the system, the screen locks and there is a message saying that the unlocker is broken so that I can only unlock it from a terminal login. But if I do that, there is still nothing working when I come back to the session that crashed. Choosing the option on the crash report to restart the program just results in it crashing again.

- Unusual behavior I noticed:
 It happens every time I try it, since I restarted the system after having some updates applied. (I tried to suggest that this might be a duplicate of 372352 but the crash reporting assistant didn't seem to accept that and insists that I haven't selected a duplicate, so I'm mentioning it here instead.) There we a lot of updates and I had the impression that they finished more quickly than usual, so I don't know if that implies they didn't work properly, but there were no error messages in the "Discoverer" program.

The crash can be reproduced every time.

It's related to upgrade from nvidia-304=304.131-0ubuntu3 to nvidia-304=304.132-0ubuntu0.16.04.2 (or, maybe, other versions in your case). You can (temporarily) downgrade your ndivia package as workaround. Also, please support this Ubuntu bug-report: https://bugs.launchpad.net/ubuntu/+source/plasma-workspace/+bug/1640451 -- to make it confirmed.
