I've just uploaded wxwidgets3.0 3.0.4+dfsg-9 which includes a patch so the user should at least now get an error message instead of a segfault (patch originally from Scott Talbert):
| wxGLCanvas is only supported on X11 currently. You may be able to
| work around this by setting environment variable GDK_BACKEND=x11 before
| starting your program.
Cheers,
Olly
