Description of problem:
I noticed this problem at least during the RH9 betas, but I forgot to
image.py line 410, if you click "OK" it kills the installer despite
what the dialog text says. notting confirmed that clicking "OK"
returns 1, which is the opposite of what the "if" conditional wants.
I noticed there is also a similar case of "Ignore" "Cancel" at the
manual partitioning screen and it does not like something about your
partition table. If you click "Cancel" it goes ahead anyway. This
may be another case of reversed logic.
Fixed in CVS (although I changed the wording and code around a bit)
