-- Information about the crash:
- What I was doing when the application crashed:
openin one of the listed apps. These has started since I upgraded from 19.04 to 20.04, I may have purged some needed dependencies in the process, I had a problem with dpkg that I fixed with uninstalling a bunch of packages

The crash can be reproduced every time.
