This is already fixed in 2.1.1 patched: please see the resources the 
posting guide and FAQ ask you to consult _before_ sending a bug report!

     o	File creation errors in pdf(), postscript(), xfig() resulted

As the FAQ says

   If a bug has already been reported or fixed, please do not submit
   further bug reports on it.
