Application: plasma-discover (5.9.4)

Qt Version: 5.7.1
Frameworks Version: 5.31.0
Operating System: Linux 4.10.0-19-generic x86_64
Distribution: Ubuntu 17.04

-- Information about the crash:
This app crashed when installing an application from the store. This is a common occurence. It also often crashes when uninstalling applications. Another issue I have is that the cursor will freeze such that it is in text-selection mode and I am unable to click on anything within the discover application. I experience crashes with the discover app very regularly.

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