GTK problem when testing Sun Studio IDE on snv_77 with jdk1.6 using Gnome window manager

This bug was found when we were testing Sun Studio IDE on snv_77 with jdk1.6
using Gnome window manager. It is not reproducible if switch to
jdk1.5.0_13 (sunstudio --jdkhome /usr/jdk/jdk1.5.0_13)

There are two issues for this bug:

1) from the console:

% /net/guild.sfbay/export/home1/common/shared_dist/sstrunk/build4.4_SXDE/inst/intel-S2/bin/sunstudio --userdir /tmp/1129-ss

(<unknown>:19201): Gtk-WARNING **: Attempting to add a widget with type
GtkButton to a GtkComboBoxEntry (need an instance of GtkEntry or of a
subclass)

(<unknown>:19201): Gtk-CRITICAL **: file gtkwidget.c: line 3236:
assertion `GTK_WIDGET_ANCHORED (widget) || GTK_IS_INVISIBLE (widget)' failed

(<unknown>:19201): Gtk-CRITICAL **: file gtkstyle.c: line 5879:

(<unknown>:19201): Gtk-CRITICAL **: file gtkstyle.c: line 5879:
assertion `style->depth == gdk_drawable_get_depth (window)' failed

2) from the IDE UI, NPE stack trace and evaluation are in CR 6633364
   Synopsis: NPE on selecting target for D-Light

While testing Sun Studio IDE (based on NetBeans 6.0)
for SXDE 1/08 (snv_79) with jdk1.6 in Gnome Window Manager,
we found out that any extended UI may cause NPE. As a result,
CR 6633364 (compiler_tools/ide/d-light) was filed and a
workaround was applied to this problem.

Subsequently, we filed CR 6635110 (jds/gnome/gtk+),
in the hope that the root cause of CR 6633364 can be fixed.
However according to the gtk developer, this is not
a GTK bug.

Andrew has done further investigation and it seems that the
bug is originated from jdk 1.6.

I coould reproduce this bug as well simply using firefox and launching some Java apps: we are using WorldServer which contains some explorer applet (see screenshot). Here are the exeptions generated:

I am using as well the default gnome environment, and my java version is:
java -version
java version "1.6.0_03"
