-- Information about the crash:
- What I was doing when the application crashed:
I typed on Settings, then I typed over a ppa to delete it because of the
previous Bionic release, and disover crashed soon after. Then, I run again
Discover so I typed on Settings and it crashed again.
The crash can be reproduced every time.
