Description lexaxelaexl 2018-01-19 13:14:45 UTC
Application: plasma-discover (5.11.5)

Qt Version: 5.9.3
Frameworks Version: 5.42.0
Operating System: Linux 4.13.0-26-generic x86_64
Distribution: KDE neon User Edition 5.11

-- Information about the crash:
- What I was doing when the application crashed:
Browsing "plasma addons" (just scrolling with mouse). My CPU was in normal use (around 30%), I had just Firefox opened. My Neon installation is almost clean (I installed it yesterday). I also opened Synaptic couple of seconds before crash. I'm not shure about distribution method, so I left it blank.

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