Description Antonio Chirizzi 2017-07-23 15:22:05 UTC 
Application: plasmashell (5.8.7)

Qt Version: 5.6.1
Frameworks Version: 5.36.0
Operating System: Linux 4.4.0-83-generic x86_64
Distribution: Linux Mint 18.1 Serena

-- Information about the crash:
The system was suspended. The crash happens many times when coming back from suspension, even though no major prolems are noticed: the message that it crashed is available on the toolbar though.
Please note this is a Lenovo P50 with the nvidia graphics card. I have had so many problems trying to make it work with 2 additional 4K monitors that I really want KDE to work properly.
In this case the laptop was on the battery, and no monitor has been attached in the last

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