Sentry Crash Report:

Description gilbert.drew 2018-01-25 08:37:36 UTC 
Application: plasmashell (5.11.5)

Qt Version: 5.10.0
Frameworks Version: 5.42.0
Operating System: Linux 4.14.14-1-ARCH x86_64
Distribution: "Arch Linux"

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

Shorly after the desktop had loaded, the weather widget showed that it was unconfigured, which was strange as it had been configured previously.  I right clicked it to enter the settings.  I typed my city name in the search and it returned a list of results.  Whilst looking at them plasma crashed.

The crash does not seem to be reproducible.

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

crash is actually in the phonon vlc backend, it was probably trying to do a sound notification
