gtk-demo core dumps

[The Surprises <thesurprises1 comcast net>]

Hello,
I'm trying to upgrade to gnome 2.6 using garnome 2.5.92.  I compiled
mostly everything in platform.  Once compiled, I tried to run the
new gtk-demo.  The main window opens, but if I try to do anything, it
core dumps with the following errors:

Xlib: sequence lost (0x10000 > 0x6f1) in reply type 0x0!

Gdk-ERROR **: The program 'gtk-demo' received an X Window System error.
This probably reflects a bug in the program.
The error was '61'.
  (Details: serial 2055 error_code 61 request_code 7 minor_code 224)
  (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.)

Thanks for any suggestions,
