Joomla 1.5 to Drupal 7.9 warning upon data import (for mysql database)

I created a fresh Drupal 7.10 installation and the first thing I did was install the Joomla to Drupal module. I imported the MySQL db to my local machine and then pointed the module to the db on my local machine. It looks like it imported all of the users, content, and categories successfully:

Processed 5 users (5 new, 0 duplicates found, 0 updated, 0 errors)
Processed 7 sections (7 new, 0 updated, 0 errors)
Processed 9 categories (9 new, 0 updated, 0 errors)
Processed 158 content items (158 new, 0 updated, 0 errors)

but I got the following warning:

Warning: Parameter 2 to joomla_myblog_joomla() expected to be a reference, value given in module_invoke_all() (line 818 of /Library/WebServer/Documents/jamesstreetassoc.com/includes/module.inc).

It looks like the content is all there, so this is a minor issue, but I wanted to make you aware of the warning.
