After that I used gdm to login into Gnome, opened a terminal and it produced the given bug. So there really seems to be something inside the Gnome-environment that causes problems. -- [jaunty] can not login using ssh anymore https://bugs.launchpad.net/bugs/328277 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to seahorse in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
