Actually I was pretty sure that my approach is bullet-proof, but perhaps
I do not get where the trap is hidden. As far as I understand, Seth
experienced problems when pcbnew (wxWidgets/gtk2) loaded wxPython shared
libraries (wxWidgets/gtk3), which end up in symbol conflicts.

This issue is eliminated in my branch by ensuring KiCad requests the
same wxWidgets flavor as is used by wxPython. I might be lacking
explanation skills, but code is unambiguous - have a look at [1], lines
746 and 775.
