TOPIC: Odd error returns 2.7.0h

I've decided to go with a development and production environment now with our site and noticed something when I upgraded to 2.7.0h on the dev site. In the records and csv export functions I get the following error:

Fatal error: Cannot access empty property in /[joomlaroot]/administrator/components/com_dtregister/models/member.php on line 134

Here's what I did to make the DEV site:
copied the joomla directory to a new location
used mysqldump and mysql to copy the database to a new database
changed configuration.php to reflect the new database name and user
updated apache config to point dev site to new directory

Upgraded to 2.0.7i on the dev site, still getting the same error. How long are tickets taking now adays?

We have the same error on our site and have logged a ticket as well.



Running 2.7.0i on Joomla 1.5.22 (Stable)
