I will have to build VTK CVS to be able to test this (I currently have
5.4.2 on all platforms).  Hopefully I can reproduce the crash, in
which case I have a better chance of being able to diagnose it.  I'm
currently swamped, so this is not going to happen very soon.

Please continue with your own debugging in the meanwhile.  First thing
you could try, is to modify the attribList to contain only
wx.glcanvas.WX_GL_DOUBLEBUFFER bringing it more in linux with
wxVTKRenderWindow.

Good luck,
