Yes, I’m having same problem in WPMU 2.8.4a and buddypress 1.1.3. Looks like this might have been addressed once at beginning of year (https://trac.buddypress.org/changeset/1083), but it’s cropped up again?

Moderators: should we post as bug?

The resolution from apeatling (in response to https://trac.buddypress.org/ticket/1356):

If you are allowing @ symbols in usernames, then please add this to your wp-config.php:

define( ‘BP_ENABLE_USERNAME_COMPATIBILITY_MODE’, true );

Worked for me!

For anyone concerned, I encountered the same problem reported by outolumo and can’t happen to use the workaround. I submitted to TRAC…https://trac.buddypress.org/ticket/1356. Will see what happens!
