FYI: ssh X forward behavior

The program 'gaim' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 207 error_code 3 request_code 2 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error()
function.)

Any ideas?


From: Etan Reisner ssh changed some of it's options "recently" so that -X no longer forwards X the way it used to. ssh -X forwards in some sort of 'safe' mode which doesn't allow apps to do certain things they might want to do. Try ssh -Y which "[e]nables trusted X11 forwarding" according to the manpage.


The man page of ssh says to be cautious of the -X option, and does not mention any caution next to the -Y option. Perhaps that could use some clarification upstream, and we should mention this change of behavior in FC's release notes?
