Strange things with client-server in 24

Strange things with client-server in 24

[Kamil Jońca]

1. Run emacs24 with server on machine A
2. From machine B try to ssh -X A
3. run something like "emacsclient -c -d ${DISPLAY} -n"  within ssh
    session created earlier.
    (so far everything works ok - I have frame on machine B, and can switch
    to gnus buffer, for example)

4 C-x/C-c or C-x 5 0  - frame disappears
5. Then I try to exit ssh sesion, but session cannot disconnect - it
   looks like that emacs server still used it somehow. 
6. When I kill ssh on machine B, then emacs on machine A disappears :(

What am I missing?

Retirement means that when someone says "Have a nice day", you
actually have a shot at it.

It looks like emacs without gtk behaves better - no hangs.

Yeah, this is a known issue with libgtk.  It gets very confused by being
abruptly disconnected from an X server (including machine B's X server
in your scenario).  Emacs is probably the only GTK-using application
that has the ability to attach to and detach from X servers, so don't
expect a fix. :-/

Emacs with ./configure --with-x-toolkit=no is very nice, and is fully
functional as an X application.  It's particularly nice if, like many of
us here, you don't care about having a tool bar or menu bar.
