Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-28-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
what i did before the crash was unplug my second monitor because i somehow got a error from changing its resolution and it made both monitors turn black and stay black, i waited for a bit but to no avail, it would not come back. so i unplugged the second monitor and restarted figuring it would fix the issue, then this crash happened

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
