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.
