That error appears to be an issue with your credentials for the datababase, if you can reliably reproduce it you could troubleshoot it be editing library/Zend/Db/Adapter/Mysqli.php directly and getting it to spit out the error code and parameters used. This is something that I would really only suggest for people who really know what they are doing.
