xemacs: Fatal I/O Error 11 (Resource temporarily unavailable) on
display connection ":0.0"
I've been running XEmacs under gdb, with a breakpoint at
x_IO_error_handler. I've gotten two different stack traces. The first
one looks like this:
#0 x_IO_error_handler (disp=0x8a04a00) at device-x.c:116
#1 0xb7cef322 in _XIOError () from /usr/lib/libX11.so.6
#2 0xb7cf789c in _XReply () from /usr/lib/libX11.so.6
#3 0xb7ce3fe2 in XQueryColor () from /usr/lib/libX11.so.6
Could we have an xdpyinfo for the display, please? Do you do anything
special with the visual (TrueColor, DirectColor, etc) of the display
that you know of?

#2 0xb7d8889c in _XReply () from /usr/lib/libX11.so.6

How up-to-date is your X11 installation? I'm seeing all kinds of
problems recently that never happened before on Gentoo and MacPorts,
and our code in this area hasn't changed in years. My feeling is that
X.org is assuming everybody uses GTK+ or Qt nowadays and keeping
backward compatibility with Xt apps doesn't matter to them.
