Description of problem:
F11 beta installer crashes after copying live image when trying to mount the partition into which the image was copied on Acer Aspire One

Version-Release number of selected component (if applicable):
anaconda-11.5.0.38-1.i586

How reproducible:
100%

Steps to Reproduce:
1. Create bootable USB stick with livecd-iso-to-disk
2. Boot.
3. Open terminal and as root rmmod acer_wmi to enable Network Manager
4. Connect to my wireless network
5. Begin install process
6. Select an existing (ext3) partition to receive the new image
7. Select ext3 as format for that partition
8. Select no installation of boot loader 
9. Process proceeds; progress bar gets about 95% drawn as live image is copied
  
Actual results:
Error dialog
Title: Unable to mount filesystem
Text: An error occurred mounting device /dev/sda10
      as /: mount failed: (2,None). This is a fatal error
      and the installer cannot continue.
      Press <Enter> to exit the installer.

Expected results:
A nice, new ext3 filesystem with a working F11 beta

Additional info:
Has happened four times. Re-imaged USB stick twice and verified the contents.

Probably not related, but I also tried to format the partition as ext4, but system wouldn't let me with no bootloader. I have /boot on a separate partition, and generally don't like grub messing with it; I update it manually.
