This is a fresh bug in revision 4391.
When trying to access the configuration page ( /administrator/index.php?option=com_virtuemart&view=config ) I receive the following error:
QuoteFatal error: Class 'shopfunctionsF' not found in /home/semineem/public_html/administrator/components/com_virtuemart/models/user.php on line 33
Cheers!
