Regarding the comment 7 in the bug:

>> I cannot reproduce this with
>> Xnest -ac :1 & DISPLAY=:1 matchbox-window-manager & DISPLAY=:1 jamvm
>> klurfe.Main
>> In 256 color mode. 

Xnest proxies the X stuff to your desktop X server whereas Maemo uses
Tiny-X configuration of the X server (i.e. "another" X server) with
limited set of extensions. In Maemo SDK Xephyr can be used to have
the correct X server and extensions. This is the first difference.

Second is that the Maemo X server runs in 16-bit, the sapwood Pixmap
based theme-engine supports only 16-bit, and I've understood[1]
that the bit-depth and what is used in requesting the "default" bitdepth
are somehow related to this bug.

There is a dirty trick you can try:
s/sapwood/pixmap/ on gtkrc file and delete the gtkrc.cache

Or then just symlink /usr/lib/gtk-2.0/2.4.0/engines/libpixmap.so to
libsapwood.so a trick we tried with Maemo+Gazpacho

If this helps, then we will know for sure that it is about the
bitdepth. 

[1] I dimly remember seeing something about that in the Maemo bugzilla
