Description of problem: Anaconda exception using custom partitioning. How reproducible: Install F8 with default disk layout + partition for /home. Install F8 again this time choose custom disk config and setup the existing partitions to be reformated with the exception of /home. I think I missed off assigning /boot. Click Next get the attached exception.

I seem to be getting something very similar, using the KDE LiveCD. However, I don't even need to do any custom disk config, but I started with a totally wiped disk that had no partition table at all. Anaconda correctly warned me about having to create a whole new partition table, but then when it was supposed to do the partitioning, it warned that it couldn't invalidate the kernel partition support on /dev/sda2 (which didn't exist originally, so I'm not surprised - you need to open /dev/sda). I pressed "ignore", but that just caused an exception when trying to actually mount the newly created partitions. Re-doing the install didn't help, but rebooting the box entirely did: at that point the kernel noticed the new partitioning and it's now installing.
Actually, I see what's going on here. Fix coming up in a minute.
Okay, tested and works. Fix committed to CVS and should be in rawhide of tomorrow
