Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-45-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
System will not come up after rebooting after patching to new kernel.  Must run startx from CLI to get any desktop. Two more plasmashell crashes in quick succession after this one:
Executable: plasmashell PID: 2714 Signal: Aborted (6) Time: 11/9/16 18:37:53
Executable: plasmashell PID: 2755 Signal: Aborted (6) Time: 11/9/16 18:37:54

The crash can be reproduced every time.

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