Description of problem: Very recently various programs started doing that after attempts to display on a remote X-server $ gnome-terminal The program 'gnome-terminal' received an X Window System error. This probably reflects a bug in the program. The error was 'BadImplementation (server does not implement operation)'. (Details: serial 658 error_code 17 request_code 155 minor_code 10) This does not happen with all programs. For example - mozilla, firefox, xterm are not affected. Also nothing like that shows up with FC3 installation which is using gnome-vfs2-2.8.2-8. gnome-vfs2-2.8.2-10 is a guess for two reasons. One is that it was recently updated and there was no such trouble a few days ago and two - it seems that only programs which are using it show such behaviour. Version-Release number of selected component (if applicable): gnome-vfs2-2.8.2-10
gnome-vfs2 shouldn't affect X stuff at all, so I doubt this is related to it. Sorry for ignoring this bug so long, but I think this has been fixed by now (haven't seen other reports), so I'm closing this.
