 Hello,

 I'm not aware of any crashes in wxGrid.

 I'm afraid you would need to debug this yourself. The first step would be
to build a version of wxWidgets with the debug symbols, so that you could
get some more useful information out of the stack trace.

 It's possible that this somehow breaks wxGrid assumptions and results in
dereferencing an invalid pointer in DoHideCellEditControl(). But it would
be really better to just see where exactly it crashes rather than try to
guess.

 No, sorry. This would be a question for the wxPython developers.
