indicator-appmenu does not display correct close,min,max buttons in any theme except Ambiance and Radiance

[Paul Hinchberger III]

Binary package hint: indicator-appmenu

Ubuntu 11.04 Natty (development branch)
indicator-appmenu 0.1.97-0ubuntu1

With the default install of Ubuntu, the appmenu's close, minimize, and maximize buttons match the un-maximized window's close, minimize, and maximize buttons. It's expected that appmenu would pick up these buttons from the GTK theme. However, if you switch to any theme other than Ambiance or Radiance, these buttons DO NOT match. In fact, it looks as if they are pulled from a common fallback default.

Customizations that aren't expected to affect this, but may or may not do so:

I have Gnome's DPI set to 144
My xorg.conf uses Option "DPI" "144 x 144"
/home is mounted from an NFS server that exports its /home with root squash
