Bug#339965: gdm: Complaining of wrong permissions on .dmrc

[Tim Van Holder]

I see the same problem, on a purely local /home (so it's not
NFS-related).
gdm incorrectly complains about .dmrc's permissions while
they're set exactl like it says it wants (and with a minor
spelling error in the English dialog: "sould" instead of
"should").
Removing group write permissions from the homedir "fixes" it,
but seems unacceptable to me - gdm has no reason to dictate
how I manage my system's groups, especially not on the level
of home directories (I can accept that it wants a specific
mode for its own config file, but no more).
