Hi Benjamin,

And thank you for investigating the issue, reporting it and preparing the patch. 
I'm not sure that disabling wxagg is always ok. I would put its disabling as an 
option for now and try to find out more about this issue.

I'm puzzled! Why should there be any need for accessing X? Did you enable tests?

Yes, SETUP.OUTPUT was intended just for me. I'll correct this. However, could you 
please send me a SETUP.OUTPUT containing the error.

Best regards,
