It turns out that I have the partner repo both enabled and disabled at the same time; that is, software centre has screwed up my sources.list. This has been reported as #871592.
It would have been better to say that *I* did not enable the partner repo. I have reproduced this bug in a virtual machine on both 64 bit and 32 bit; in both cases I performed a fresh install only for the purposes of checking this. And in both cases I was presented with the two icons. Both times I used beta 2 install medium.
