BP Corporate update for BP 1.5 killed my site

Not sure if it is just going to be my setup (because plugins and such)

But the update to BP Corporate killed everything on my site, I'm reporting this just in case.

The activity stream page show a fatal error:

Fatal error: Call to undefined function bp_core_avatar_thumb_width() in /home/teatrade/public_html/wp-content/themes/bp-corporate/activity/post-form.php on line 18

All the other BuddyPress pages failed to load anything beyond the header.

Rolling back to the previous version for now.
