Comment 13 for bug 1164592

Probably not at all helpful, but I'm doing some retesting this AM with 20130423.2 i386, and this appears to be the only function that's broken. Even alongside installs work as they should if sufficient free space is available.

That is, the Continue button changes to Install now as expected and the installation runs as it should. So it's only the "resize" window that's borked.
