just out of curiosity: is there something missing for this patch or  
did it get 'lost'?

The segfaults that were mentioned earlier are not caused by this  
patch: I see it happening as often with as without the patch; I think  
it's more likely an issue in another, underlying library (not even wx  
I think).

So the patch in itself is not a problem at all and does not cause any  
issues (that I would be aware of).
