-- Information about the crash:
- What I was doing when the application crashed:
– Opened Discover
– Searched for 'chromium' and selected the snap version (chromium is already installed)
– Pressed 'Configure permissions…'
– Checked one of the unchecked options ('mount-observe')
– Crash

The crash can be reproduced every time.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
