-- Information about the crash:
- What I was doing when the application crashed:
the application window closes and a message appears with the buttons "restart" and "error report".

- Unusual behavior I noticed:
go to "work environment behavior", then "screen locking", then the "configure" button; now select any other workspace settings tab and get an error.

- Custom settings of the application:
nothing.

The crash can be reproduced every time.

-- Backtrace:
