app crashed after a few minutes

[Elias Chatzigeorgiou]

installed Pinta on Debian 10 (buster) using:

https://notesalexp.org/packages/en/buster/amd64/pinta/

Played a little with the mouse, draw some sketch and played with the filters.
All seemed fine until I tried opening a file, which caused a majestic crash
as reported below:
