[PD] pyext detach method crashes pd with gem/pdp

[vincent rioux]

hi all,
i just noticed that the detach method of pyext can cause pd to crash.
i had a patch with gem, pdp and pdp2gem and as soon as i tried to 
display video from pdp into gem display, pd crashed. spent quite a hard 
time (not too long though) to find out why this happened.
the solution is the following : comment out the self._detach(1) in pyext 
files.
best,
vincent
