Tag fails due to chdir to non-existent dir

[Chris]

Hi,

I'm trying to tag a whole repository with the following command:
cvs -q tag jpred2_final
But it aborts with the following message:
cvs [tag aborted]: could not chdir to jlvw: No such file or directory

Which is indeed true there is no 'jlvw' and nor has there ever been. Why 
 does CVS think that this directory exist and needs to be tagged? I've 
looked in the CVS repository and there is definitely no directory name 
'jlvw' there. Is there a way to force CVS to skip over this?
TIA

Chris.
