Application: plasmashell (5.13.5)

Qt Version: 5.11.1
Frameworks Version: 5.52.0
Operating System: Linux 4.18.18-200.fc28.x86_64 x86_64
Distribution: "Fedora release 28 (Twenty Eight)"

-- Information about the crash:
- What I was doing when the application crashed:  I was attempting to open Xsane via the start menu but accidentally selected the Internet program group rather than Graphics.  When I attempted to switch to graphics Plasma crashed just as I was about to hover over the Graphics menu entry.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
