According to my logs robots.txt is causing this error:

warning: Cannot modify header information - headers already sent by (output started at /home/drupal/includes/bootstrap.inc:546) in /home/drupal/includes/common.inc on line 139.

Severity is listed as error.

I added an explicit exit; after the robots.txt file is printed. This should solve the problem. Please test and close.

Sorry, I made a mistake, though I disabled robotstxt.module, the error persisted, it occurs only with anonymous users or when you first login. I'll try to disable and enable modules again to better narrow it down.
