When I went to bug #7537 and clicked on "Show dependency tree", I got:
Bugs that bug 7537 depends on
Bugs that depend on bug 7537
select bug_id, bug_status, assigned_to, short_desc from bugs where
bug_id = 7602 and bugs.groupset & = bugs.groupset:
parse error near '= bugs.groupset' at line 1 at globals.pl line 61.
For help, please send mail to the webmaster
(firstname.lastname@example.org), giving this error message and the time and
date of the error. ;
This should be fixed now. Thanks.
