Comment (by mojca@…):

 Yes, most probably this is related to incompatibilities with wxPython 2.9,
 but this means that the software needs to be fixed, sooner or later. The
 first few warnings related to mouse have already been fixed (in 2.9.5; the
 patches have also been backported to wxWidgets 2.9.4 port, but I forgot to
 add them to the new wxPython package and I will add them back now before
 switching the whole wxWidgets mess).

 I've seen the error about m_cols before in other software.

 Anyway, {{{grass64}}} or whatever other files from grass need to be fixed
 to call the right Python. This is independent from the errors I
 encountered.
