Hi Martin,
I will report your error to mart-dev@ebi.ac.uk. This is the e-mail  
list you should use to report errors relating to the www.biomart.org  
martview and martservice. Unfortunately, you cannot access the ensembl  
server using the BiomaRt package at the moment as there has been an  
error in the registry. We plan to rectify this for the forthcoming  
release due at the beginning of March. I think you should use the  
ensembl.org mart interface or the martservice until the bug is fixed.
I hope that helps,
Regards,
Rhoda
