Error on signup page.

I'm receiving the following error on my new user signup confirmation page.

Warning: array_merge() [function.array-merge]: Argument #1 is not an array in /home/scrapblg/public_html/wp-content/plugins/buddypress/bp-xprofile/bp-xprofile-signup.php on line 261

I'm using the BP Corporate theme. How do I fix this? Thx.
