            Bug ID: 102639
           Summary: BadLength (poly request too large or internal Xlib
                    length erro
           Product: Mesa
           Version: 17.2
          Hardware: All
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: GLX
          Assignee: mesa-dev at lists.freedesktop.org

This error has returned after maybe five years.

I tested 17.1.8, 17.1.9, and 17.2.0 in i686 and x86_64.
The app that crashes is the gtk2 color changer and pixpbuf demos.
I tried no other gtk apps. Glxgears works. The demos crash at startup.
What should have happened: color-chooser should appear or pixbuf demo should
appear. To reproduce: run gtk-demos (gtk2) and select those demos.

The program 'gtk2-demo-64' 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'.
  (Details: serial 2460 error_code 16 request_code 72 minor_code 0)
  (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.)

The serial number changes, but the rest is the same.
