System uses 1 ATA/IDE disk which contains grub and a Windows partition and 2 SATA disk in an nvidia_raid that contains a Fedora 11 installation. Whenever the nvidia raid is selected for installation the installer stop with the attached messages.

Thanks for the bug report!
Note to self here is what happening:
1) Due to the fix for bug 583484:
pyblock no longer creates a mapping, and thus a device node for the extended partition itself
2) This means the extended partition does not get added to the device tree
3) This causes this backtrace when auto-partitioning tries to remove the extended partition (as after clearing partitions it is empty).
Make pyblock create a mapping for extended partitions again, but this time one which is compatible with kpartx's mapping to avoid bug 583484.
I hope that your nvidia raid is still in the condition which triggers this fault, I'll provide you with an updates.img with a proposed fix to test this.
This is fixed in python-pyblock-0.48-1.el6, moving to modified.
Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
