Strange Output In Dashboard Marketpress

I was just working on a site and I had to change a password for a user.

Upon going into the users details I see this in the page generated :

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home4/y6hb84k7/public_html/wp-admin/includes/template.php:1698) in /home4/y6hb84k7/public_html/wp-content/plugins/marketpress/marketpress.php on line 989

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home4/y6hb84k7/public_html/wp-admin/includes/template.php:1698) in /home4/y6hb84k7/public_html/wp-content/plugins/marketpress/marketpress.php on line 989

I have attached a screen shot of this fine action below.

This is a multi-site install and marketpress is enabled on this one site only so far and it is not the root site... thought to add that in in case it helps with diagnosis.

Cheers
