Title:
  Output buffering issue when error occurs during Plugin Upgrade

Status in Open Source PHP RAD Framework with UI.:
  Confirmed

Bug description:
  If an error occurs in a plugin's upgrade script, due to a malformed or
  problematic SQL statement for example, an exception is thrown and
  displayed as one would expect. However, when FirePHP is enabled and
  attempts to log the error the HTTP header is already sent which leads
  to the following error:

  Headers already sent in
  /var/www/mysite/includes/PHPDS_template.class.php on line 989. Cannot
  send log data to FirePHP. You must have Output Buffering enabled via
  ob_start() or output_buffering ini directive.

  To conclude, it seems that the output buffer is flushed when an
  exception occurs, the error html is then rendered and then FirePHP
  attempts render its own output while making changes to the HTTP
  header. To reproduce the error simply provide an erroneous SQL
  statement in the plugin's XML script in the upgrade section.
