Description of Problem:
The following traceback occurred while adding a partition.
Steps to Reproduce:
1. TUI install
2. Auto-partition + clear all partitions
3. review the partition map and add a partition to available free space
   by hi-lighting it and typing <Enter>
4. specify the size of the partition in MB (not cylinder boundaries)

I received this traceback while trying to create a 6000M partition in
the 6600+ megs available.  This is not an issue w/ GUI installs because
you can't specify the size of the partition when it is created in this
manner.

Version-Release number of selected component (if applicable):
build re0904.0
anaconda-7.1.95-2.i386.rpm

How Reproducible:
100%

Additional Information:
The system has 2 8675M SCSI drives.
Auto-partitioning resulted in the following map:
            start    end    size    type    mount
/dev/sda
     sda1     1       6      47M     ext3    /boot
     sda2     7       260   1992M    swap
Free Space    261     1106  6636M    Free Space

/dev/sdb
     sdb1     1       1106  8675M    ext3     /

Adding the partition works w/out error if I accept the default settings
in the dialog box.  Similar tracebacks occurr if I try to add partitions
as small as 3000M. I was able to add a 2000M partition in this manner.
Seems to be independent of installation type -- verified w/ FTP and NFS
installs.
