Sentry Crash Report:

Description Philip Muškovac 2016-01-08 17:31:12 UTC 
Application: plasmashell (5.5.3)

Qt Version: 5.5.1
Operating System: Linux 4.3.0-5-generic x86_64
Distribution: Ubuntu Xenial Xerus (development branch)

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

Do a package list refresh with "apt update" or so.
When muon-notifier tries to inform you of potentially available updates it crashes instead.

Happens since the the update to plasma 5.5.2, but apt was updated around the same time so might be related.

Versions:
kubuntu 16.04 dev
muon-discover: 4:5.5.3-0ubuntu1~ubuntu16.04~ppa2
apt: 1.1.10
qtbase: 5.5.1+dfsg-10ubuntu2

Plasma 5.5 packages for 16.04 are available in ppa:kubuntu-ppa/ppa-landing at time

The crash can be reproduced every time.

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