= bug description =

After the change for #423, the configuration options for bugzilla's XMLRPC interface changed from BUGZILLA_URL to BUGZILLA_XMLRPC to get rid of the hardcoded partial url in our templates.

Unfoturnately, the sync code is still using 'BUGZILLA_URL' and with an updated config, sync blows up with errors.

To work around this bug, I've kept the old value for 'BUGZILLA_URL' which allows sync to work but has the side-effect of breaking display of the tracker bugs.

= bug analysis =

All references to 'BUGZILLA_URL' and 'BUGZILLA_XMLRPC' need to be checked to make sure that we're getting the right urls in the right places.
