Crash after copy into new image

[grofaty]

I have downloaded Pinta 2.2-development on Ubuntu 22.10 from Github: https://github.com/PintaProject/Pinta/actions/runs/4525610835 master branch.

1. I have made a selection with CTRL+A.
2. Copy image with CTRL+C.
3. Paste into new image ALT+CTRL+V and Pinta crashed in Terminal there was the following text:

I haven't been able to reproduce this yet, either on macOS or Ubuntu, but perhaps it's dependent on when the .NET garbage collector runs...

[grofaty (grofaty)]

I can't reproduce it either. Some strange crashes appear in Pinta 2.2-development and I can't reproduce them.

[Cameron White (cameronwhite91)]

I can reproduce now with some local changes that run the garbage collector much more frequently. I think there is an issue with some of the manual GTK bindings I did for some missing functions in the gir.core library

I think this should be fixed by https://github.com/PintaProject/Pinta/commit/3d893d17ab17dec62e74896405d6dc39688f8e7e, but please re-open if you still run into the crash again!
