problem with wxPython 2.8.4.2 on Mac

[Michael Barton]

Some javascript/style in this post has been disabled (why?)

I recently updated from wxPython 2.8.4.0 to 2.8.4.2 on my Mac, using the binaries supplied at the wxPython site.

After updating, wxgrass crashed with the error listed below. After I uninstalled 2.8.4.2 and reinstalled 2.8.4.0, it runs fine.

I've posted this to the wxPython bug list too.
