The above error sounds like a wx issue not a vtk one, but indeed not one
we seem to have hit in the debian package.

I don't understand why there's a cast to (const wxChar*) there - I'd
try removing that, since that's what's causing the error - i.e. make
that line (loch/lxGUI.cxx line 517):

#define matchtype(w,t) if (fName.EndsWith(wxString(_T(w)))) return t;
