We had a problem on beet where a local user had Gnome Keyring issues when trying to commit changes to svn. It *appears* that if the local user name and the remote user name are the same, but have different passwords, things can get a bit weird. We deleted the local user's keyring, but the problem re-occurred on reboot.
When the user logged in to beet with their netlink id the problem did not occur.

Note to self - do not provision local users that have the same name as the project itself.
