When starting to install FC3 on a system (that has two harddisks, 
that are loaded with an old redhat-linux, winxp and win98) the 
installer has a parted exception and stops. 

It happens just a few steps after the graphical installsystem starts 
(after the questions about language and keyboard).

Version-Release number of selected component (if applicable):


How reproducible: Every Time


Steps to Reproduce:
1. Reboot with FC3 DVD in drive
2. Start installing with graphicall installer
3. After country/keyboard questions a popup named "bug" warns 
thatthere has been a parted exception and offers the choice to ignore 
or cancel. I choose ignore.
4. Another popup shows, also named "bug" also with a warning 
concerning a parted exception with also the choice ignore and cancel. 
I choose ignore.
5. Installer shuts down (shows the system shutdown, and the 
message "it is now safe to reboot").
    
  
Actual results:


Expected results:
Probably the partition-editor should have started at this point.

Additional info:
The ALT-F1 screen has this info (I had to write it down and now type 
it out since copy and paste were of no use, so pardon the 
spelling/other small mistakes there might be):
