Sentry Crash Report:

Description Alexander Kernozhitsky 2018-12-28 15:13:54 UTC
Application: plasmashell (5.14.3)

Qt Version: 5.11.2
Frameworks Version: 5.51.0
Operating System: Linux 4.19.0-1-amd64 x86_64
Distribution: Debian GNU/Linux buster/sid

-- Information about the crash:
Hello,

I was trying to configure the icon for the application menu. I went to application menu confguration and got to the icon chooser dialog. But it crashes if I try to select any icon category other than Applications.

I am using Papirus icon theme, and this bug is not reproducible with Breeze icons.

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".
