debugging output from Anaconda crash

Description of problem:
From the Fedora 11 x86 KDE Live CD, I tried to install Fedora to my harddrive. In my partition setup, I had a filesystem (/dev/sda6) mounted as /home/notroot/shared and another (/dev/sda2) as /home. When Anaconda tried to umount /dev/sda2 (/home), it ran into an error: it could not umount /home because there was another filesystem, /dev/sda6 (/home/notroot/shared), mounted under it. 

Version-Release number of selected component (if applicable):
11

How reproducible:
every time

Steps to Reproduce:
1. Boot Fedora 11 KDE Live CD (or probably any other Fedora 11 installation media)
2. Mount a filesystem somewhere when creating the partition layout and mount another as a subdirectory of the former filesystem's mountpoint.
3. Continue through the installation process.
  
Actual results:
Anaconda crashes during the post-install operations.

Expected results:
The post-install operations work.

Additional info:
I opened a Konsole window and ran su. I tried umounting /mnt/sysimage/home but got an error saying the filesystem was busy. After successfully umounting /mnt/sysimage/home/notroot/shared, I umounted /mnt/sysimage/home fine.

Trying to install Fedora again but without telling Anaconda to mount /dev/sda6 as /home/notroot/shared worked fine.
