Description of problem:
The installer starts up, and in text mode I select the language (en), NFS
install, DHCP (ipv4), and the path.  Then X starts.  I can view the release
notes with no problems.  When I click "next" a warning dialog pops up ("This is
a pre-release, etc").  When the warning dialog is closed, anaconda crashes, with
the attached dump.

Note: I also tried a text-only install, and the same crash appears after the
"This is a pre-release..." dialog.

Version-Release number of selected component (if applicable):
This wasn't actually FC6-Test3, but the FC6-pre-dvd from here:
