GNOME Bugzilla – Bug 562824
gnome-keyring-daemon should synchronize XAUTHLOCALHOSTNAME and ICEAUTHORITY too

It seems that synchronizing XAUTHORITY is not enough to be 100% sure that gnome-keyring-ask can access the display. See https://bugzilla.novell.com/show_bug.cgi?id=441789 for example. So synchronizing XAUTHLOCALHOSTNAME is necessary too.
Oh, and ICEAUTHORITY is needed too, it seems.
Thanks. Done.
