The following in NEWS is probably relevant:
CHANGES IN R VERSION 2.1.1 patched
o File creation errors in pdf(), postscript(), xfig() resulted
in a pointer being freed twice. (Reported by Matt McCall)
So,
1) Please try R-patched as we do ask you to (before sending a bug report).
2) You probably do not have permission to open the files in the current
directory, hence the error that is being handled twice.
