Enabling display query log in devel causes jquery is not defined error in firebug

Configuration:
Mozilla Firefox for Ubuntu (canonical - 1.0) 11.0
DrupalForFirebug 0.0.8a (DrupalForFirebug{0.0.7}_modified_for_firebug_1.9.1_0.zip downloaded from #52 apodran)
Firebug 1.9.1
Drupal 7.12 with no modifications, all modules and database are up to date

This is repeatable by turning on and off the display query log in the devel module configuration. The query log is displayed in firebug but the console reports the jquery not defined error.

jQuery is not defined error reported on line 9 (file attached) of:
Execute PHP ... Code Execute Firebug PHP ... ?q=admin/firebug/exec

...script type="text/javascript" ... jQuery.extend(Drupal.settings, {"devel":{"request_id":380912}});
