Application: plasmashell (5.10.5)

Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.14.3 x86_64
Distribution: Ubuntu 17.10

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

Hi, I just wakeup my notebook from sleep (after one hour, on different network) and Plasma crashed after unlock the screen. 
I guess that it is related with kde telepathy reconnection (it is in the stacktrace)...

The crash does not seem to be reproducible.

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