It looks like the error arises if the FD does not overwrite some files  
on restore. This confuses the PKI code and subsequent file restore  
fails also. In our case it was a fresh formated NTFS partition with a  
restore with replace=never and the hidden "System Volume Information"  
stops the restore.

There was also a report some time ago:

Should i create a bug report or have i missed something obvious?

Regards
