I've been bitten by #192099 yesterday. So far I have managed to "fix it" by installing the gdm2 woody backport, that is working fine. Are Sean's packages still available somewhere so I can enjoy a more recent gdm version? PD: Why is this important bug more than 2 months old and we have not seen a single try to fix it by the maintainer? Testing if a new version fixes it would look like me like an obvious thing to do...
