> Any suggestions about what might be going wrong here?

Could it be related to using Unity as desktop shell with a global menu, on Natty? Is there general information provided by Ubuntu about changes related to the new desktop, and/or a list of known issues?

Other applications seem to be affected by similar issues when running under Unity, e.g.:
Bug #766804 in DBus Menu: “there are missing icons in banshee menu, such as the Write CD one”
