For what it's worth, I think the severity of this bug is exaggerated. GDM is certainly not "unusable or mostly so" for any of the systems I've touched lately - indeed, this bug doesn't affect them at all.
In fact, this bug seems to be a perfect match for the "important" severity: «a bug which has a major effect on the usability of a package, without rendering it completely unusable to everyone.» But then again, I'm no release manager.. Regards, -- Tore Anderson
