Bug 399935

Application: plasmashell (5.14.1)

Qt Version: 5.11.2
Frameworks Version: 5.51.0
Operating System: Linux 4.18.14-zen1-1-zen x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to change default icon for "Application Dashboard" since it looks more like a play button, when  I clicked "select" button plasmashell froze and then segfaulted.
- Custom settings of the application:
Icons set to Oxygen, doesn't happen with Breeze.

The crash can be reproduced every time.

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