This database does not list version 2.7 for Bugzilla. This is the version I have from the RPM downloaded from RedHat (bugzilla-2.7-3.i386.rpm).
Where did you obtain this rpm? We have only shipped bugzilla out as noarch rpm's on Red Hat Powertools CD's. And I also do not see any that are version 2.7-3
RPm referenced on original bug description was created by another developer from tarball downloaded from redHat (just to make our life easier at work when installing). But the version of Bugzilla from the tarball was 2.7, and that isn't listed in this database.
The "bugzilla" Product is for issues with Bugzilla running on bugzilla.redhat.com (whic never were at version 2.7). For issues with the RPMs from PowerTools, use "PowerTools" product, "bugzilla" *component*.
