Description of problem:
Anaconda was (apparently) unable to find/recognize my grub bootloader and/or
/boot partition. As a result, it treated it as if the system had a third-party
boot loader and refused to update the config. I had an option to replace the
boot loader or skip config altogether. I selected replace, causing a traceback
and crash, which is attached.

Version-Release number of selected component (if applicable):
Anaconda 11.4.0.82, according to the traceback.

How reproducible:
It happened every time until I told anaconda to skip instead (at least 2 or 3
times).

Steps to Reproduce:
1. Somehow get into a state where anaconda doesn't recognize a perfectly valid
/boot (?)
2. Upgrade the installation.
 
Actual results:
3. See that anaconda doesn't recognize /boot, but you can replace or skip
4. Select replace, click next
5. Watch the installer crash and offer to save the traceback/debug information.

Expected results:
3. Anaconda gives you the option to update, replace, or skip
4. Selecting any of the provided options doesn't crash, but does what it says it
will.

Barring that, anaconda should never crash, ever (especially not for options it
gives me). I'm just glad it hadn't modified my disk yet.

Additional info:
This occurred when I updated my gateway machine (which has my DNS, & DHCP
server, hence the manual/IP setup) from Fedora 7 to Fedora 9. The partitioning
of the drive is from the default (or near-default) partitioning of an earlier
install, so I don't know of anything that would cause the installer to act like
it did.

Postinstall info:
