Gdk-ERROR **: The program 'system-config-lvm' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadLength (poly request too large or internal Xlib length erro'.

(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.)

I've seen such X protocol errors ever since the most recent major distro
releases (sles11, rhel6) and since F11, whenever I used a rather old X
server which did not provide whatever X extensions those recent GTK
versions seem to require. Unfortunately, GTK does not seem to check for
the required extensions but rather keeps on going and causes confusing
errors as above. I doubt that GTK would drop the requirement on those
extensions, so the only fix I could think of would be to check for those
extensions and print a helpful error message.
My workaround has been to use VNC instead. Meanwhile I have a recent X
server on my desktop which works with X11. However, for connections to
the host which have anything but very short LAN latencies, I would
recommend VNC in any case. Otherwise X11 and GTK slow down any X client
program, presumably because of many blocking round trip X11 messages
throttling program progress.
The problem is documented for RHEL 6:
"If the installer on your workstation fails because the X11 server does
not support required X11 extensions you might have to upgrade the X11
server or use VNC."
[http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/Installation_Procedure_Overview-s390-GUI.html]
Even though it's RHEL 6 documentation, F14 is extremely similar in terms
of installation.
