Which java do you have installed? The default with Ubuntu is IcedTea. Last time I checked this was working with the patch, but that could be the problem. Jmol (the 3D application that is launched) is only verified against the Oracle/Sun JavaVM. If you are using IceTea try switching to the Oracle/Sun release.
I just destroyed my Ubuntu VM so can't check this right now.
