This is a bug in wxWidgets.  Under wxGtk it doesn't fail cleanly if
OpenGL support is unavailable and you ask it to create an OpenGL
window.

There's not a lot we can do to handle this cleanly without fixing
wxWidgets I'm afraid.  I was hoping to come up with a patch to send
to them but I've been too busy recently.

It pops up in the more mundane situation where you don't have OpenGL
support installed (I hit it myself, and it's been reported on here
before).
