Description Nikolai Magnussen 2017-04-30 10:20:43 UTC

Application: plasma-discover (5.9.5)

Qt Version: 5.8.0
Frameworks Version: 5.33.0
Operating System: Linux 4.10.11-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
	I had just installed two plasmoids(termoid and todo list), and was simply searching for another package when discover suddenly crashed. I do not remember which state the display pane of the Discover window was in, but it was either the search listing or the page for the todo list plasmoid

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