gtk Failure on HP-UX - Crash in _gdk_x11_set_input_focus_safe method

Gowri Kandasamy
I am facing a failure when I run any application that uses GTK 2.6.

Used the following to build GTK2.6 : glib-2.6.4  pango-1.8.1 atk-1.9.0

The following is the stack trace when I run the gtk-demo.
When I run the demo &  move the focus to the  frame, I get the
following failure.

 Program received signal SIGSEGV, Segmentation fault
  si_code: 0 - SEGV_UNKNOWN - Unknown Error.

   Looks like the the dpy value got from GDK_DISPLAY_XDISPLAY
(display) method is not proper on HP-UX. I see the same failure in all
the appliations that use   gtk+-2.6.7 .
I see the same failure in previous gtk2.4 also. Is this a know issue ?
