It would be nice to be as uniform as possible across Python and C++. For example: renaming Squeal or the python part. I think CppErrorHandler is more clear.

If you assign an issue to you, does that mean nobody else can come in and do it? I don't know if we want to leave issues openended for anybody (to encourage others or just sharing labor) to do.

Take on other people's trackers sure, but it's good manners to ask first (in case they have already started)
