Description of problem:
The machine currently has slackware installed with all filesystems except
'/'
on reiserfs.

when using diskdruid to assingn the partitions to a filesystem this
happened:
/dev/hda1 which is ext2 now went ok justs selected the device typed '/' and
set filesystem options to reformat it to ext3.

the selecting /dev/hda2 as swap, no problems

then /dev/hda3 as /var (that currently is reiserfs) you can't enter a
mountpoint for it  because it's not a "known" filesystem so you have
to get to the filesystem options dialog to tell anaconda to reformat it
using ext2 or ext3, when you hit enter at the button the installer crashed.

all this was done using the text based installer in expert mode
and because i don't want to change the on-disk partitions i didn't delete
or
add any, I just wanted to reassign the existing ones to a filesystem and
reformat them
to ext3

How reproducible:
Always

Steps to Reproduce:
oh, please see description

Actual Results:  Installer crashed

Expected Results:  Installer popps up with the filesystem options dialaog.

Additional info:

workaround: remove all on-disk partitions, reboot.
create new disk partitions and filesystems so that 
anaconda doesn't find any reiserfs filesystems.
