Likewise. I'm sorry it's taken a while to get back to you.

You don't want to mess with the client (gv); the client may be buggy, but
the problem that hangs your session is (probably) the fault of the X
server.
The process you want to look for is XFree86-debug. If it's still running,
which it appears to be, you can use GDB to attach to the running process
and ask for a backtrace.
E.g., here's a partial transcript of me performing this procedure with an
XFree86-debug X server running in its normal event loop (where it is when
it has nothing else to do). I expect the results of your backtrace will
look a bit different.
