ADODB error?

I decided to start messing around with MT5.0RC3 and managed to get a copy of my blog converted over, but when trying to access the archives (set to dynamic publishing) I ended up getting this error about ADODB

Fatal error: Uncaught exception 'ADODB_Exception' with message 'pdo error: [-1: Invalid table name: mt_fileinfo JOIN mt_template ON fileinfo_template_id = template_id] in FileInfo::UpdateActiveTable(0, 0) ' in /home/eugenemah/cgi-bin/MT5/php/extlib/adodb5/adodb-exceptions.inc.php:78 Stack trace: #0 /home/eugenemah/cgi-bin/MT5/php/extlib/adodb5/adodb-active-record.inc.php(494): adodb_throw() #1 /home/eugenemah/cgi-bin/MT5/php/extlib/adodb5/adodb-active-record.inc.php(388): ADODB_Active_Record->Error('pdo', 'FileInfo::Updat...', -1, 'Invalid table n...', 0, 0, Object(ADODB_pdo)) #2 /home/eugenemah/cgi-bin/MT5/php/extlib/adodb5/adodb-active-record.inc.php(136): ADODB_Active_Record->UpdateActiveTable('Invalid table n...', 'UpdateActiveTab...') #3 /home/eugenemah/cgi-bin/MT5/php/extlib/adodb5/adodb-active-record.inc.php(971): ADODB_Active_Record->__construct(false) #4 /home/eugenemah/cgi-bin/MT5/php/extlib/adodb5/adodb.inc.php(2119): adodb_GetActiveRecordsClass('mt_fileinfo JO...', false, Object(ADODB_pdo)) #5 /home/eugenema in /home/eugenemah/cgi-bin/MT5/php/extlib/adodb5/adodb-exceptions.inc.php on line 78

As far as I can tell, MT5 itself seems to be working fine. This only occurs with my dynamically published archives. Using a copy of my existing DB, and publishing to new folders. Hosted on Dreamhost where phpinfo() claims to be 5.2.11. Currently running MT 4.32 without any issues. mt-check.cgi says everything is fine with the perl modules.

Haven't had a chance to dig into this more extensively yet. Wanted to see if anybody else had encountered this.

Next step I'm going to try is to see if it happens with entries in a fresh new DB
