I'd like to do the 0.40 release early next week to the wxpython,
python-list, etc, communities. Do you think it's time?
I'm reasonably happy with the backend quality for now, and I think the only way we'll start to really squash the bugs is to get more people using matplotlib.
Yes, I think it's time.
The only significant bug I'm aware of, and it's an important one, is
the problem with vertical rendering of text in the wxpython with GTK2
backend. Unfortunately, since it appears to be a known bug, I'm not
sure what we can do about it, except perhaps remind Robin Dunn and the
other wx developers about the problem.
The best approach is probably as you suggest. If we release, perhaps we can find a friendly developer of wxPython with GTK2 who can perhaps help us. I'd agree that it's a significant issue, and I guess that most newer Linux distributions have probably given up on GTK 1.2. I may reconsider whether to try to do a wxPython build linked against GTK2. Debian has a 'fakeroot' utility, which may help me.
