This really looks as a bug in wxWidgets itself.
I think it would be difficult to handle this case nicely in wxLua 
binding wrappers... it's probably better to submit a patch to wx devs 
and ask them to apply it before 2.6.3...
if those icons aren't really used it should not be a big issue just 
replacing wxCursor->wxIcon...

am I right ?
