Andre Klapper created an issue:
Would it be possible to redirect https://bugzilla.gnome.org/enter_bug.cgi?product=gnome-perl (ignoring any additional URL parameters, so for example also redirect https://bugzilla.gnome.org/enter_bug.cgi?product=gnome-perl&component=whatever ) to https://gitlab.gnome.org/GNOME?filter=perl ?
The problem with the gnome-perl Bugzilla product is it has a lot of components. These components are all separate code repositories in a Gitlab world, so I'd say this redirect would be the best solution to let bug reporters still guess/find the correct product in Gitlab.
