Crashing on a success message seems odd. ;-)
This appears to match an error message in libx11:
"XIO: fatal IO error %d (%s) on X server \"%s\"\r\n",
(I assume you're seeing the 'XIO' in your error message?)
This is in the routine _XDefaultIOError(), which is the default fatal
system error reporting routine. Says it's called whenever an X internal
system error is encountered.
So... the error message by itself doesn't tell you very much.
However, I bet if you installed debugging symbols for the libx11 package
(sudo apt-get install libx11-6-dbg libx11-xcb1-dbg) and then ran in gdb
with a breakpoint on that function, repro'd the crash, and then got a
full backtrace from that point, it'd point to how the crash is
originating.
