incorrect/misleading error message says home folder should have 644 permissions instead of 755
After logging in, this message appears:
your $HOME/.dmrc file has incorrect permissions and is being ignored. This
prevents the default session and language from being saved. File sould [sic] be
owned by user and have 644 permissions.
It's either incorrect and should read 755, or misleading for a noob who would
read it as needing to change the home folder permissions to 644 (a terrible idea
that makes ubuntu freak out) when the way to make the error message go away is
to change home folder permissions to 755.
