Hello José,

this error has happened some times before, and has been reported as
quite difficult to isolate: 
http://osgeo-org.1803224.n2.nabble.com/Fwd-Hello-td3267307.html

More hits in Google lead to qgis mailing lists.

This is a more detailed analysis on the specific Python error:
http://bytes.com/topic/python/answers/598332-ioerror-errno-4-interrupted-system-call

I'm sorry I don't have a solution ready, so I hope that adding
information to this issue will help developers (of rpy2, if I get it
right) to fix it. Of course anyone willing to provide a patch is
welcomed to propose it to rpy2 developers.

Thanks for understanding, and I hope it will be fixed asap!
In the meanwhile a virtual machine with Linux is probably the quickest
and less-effort workaround.

Anne
