It is rather presumptuous of me to comment, but for what it's worth I
personally would not ignore such a warning.  There is (it seems to me)
always a possibility that the warning is symptomatic of a problem that
could at some stage whip around and bite you on the arse.  I would try
to find out why the directory "vign_test" (unexpectedly?) exists.  Where
does it come from? Who/what created it?

If its possible existence is "understandable" perhaps you should test
for its existence (using file.exists()?) and if it does indeed exist,
don't try to create it.

Feel free to ignore me (and I'll go away! :-) ).

cheers,

Rolf
