While using Scribus, I've noticed that the Notes Styles menu can crash repeatedly in certain circumstances.
What should I do to contact the developers and help them fix this problem?
Since you did some steps to check that it's indeed a bug, filling a ticket in the bug tracker was the right thing to do
- https://bugs.scribus.net/view.php?id=17446
- https://bugs.scribus.net/view.php?id=17447
well done!
you already found the Matrix chat (https://matrix.to/#/#scribus-general-chat:matrix.org), so you're for sure on the good track : - )
