Edit// scrub this was after all the obvious and classic header already sent cause – uexpected and unrequired white space in files, my bad, looking beyond the obvious for some deeper reason

Have a slightly odd issue with header sent errors when performing any action in admin such as saving / publishing new page.

This is a clean install of BP 1.2.1 / WPMU 2.9.1.1

Issue occurs between wp-includes/pluggable.php and either a functions.php file in a child theme or bp-custom.php placed in either /plugins or /plugins/buddypress/

site frontend demonstrates no issues.

Functions.php contains simply a few custom functions such as rk_signup_redirect(), sidebar widget registrations

bp-custom simply contains an add_action to remove the Random menu

Both these files were moved over from a earlier test install bp 1.1.3 and worked without issue.

Selectively commenting out each function in both of the files to try and isolate a problem snippet proved negative suggesting a clash with calling anything from either file and WP admin .

This has me confused and not sure what else I can try in order to rectify the issue, has anyone else run across this? is it reproducible? or have I missed something?
