Description Antonio Chirizzi 2018-08-15 08:32:07 UTC 
Application: plasmashell (5.8.9)

Qt Version: 5.6.1
Frameworks Version: 5.36.0
Operating System: Linux 4.4.0-131-generic x86_64
Distribution: Linux Mint 18.1 Serena

-- Information about the crash:
- What I was doing when the application crashed:

Just put the laptop on the docking station, opened the lid, (linux was suspended), the laptop woke up, everything worked fine, showing the lock screen, on the 3 monitors (1 from the laptop, another 2 monitors attached to the docking station)
Typed in the password, the screen unlocked fine and then the sad face appeared on the low right corner...

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