I'm looking at the forums, and I'm finding it difficult to know exactly where to file bugs. There is still:
https://netbeans.org/bugzilla/enter_bug ... uct=python
Which seems a good place to continue to file bugs, and my guess is Geertjan would be up for bugs being tracked there. I can find out or help if a possibility. Anyways, it allows for those bugs to be entered as they are found in the IDE.
