Anaconda crash screendump
Description of problem:
While installing F14 TC2 x86_64 in a kvm guest, I get a backtrace. I grabbed the attached screenshot.
This happened both, when choosing the default 'Replace existing Linux setups' or when choosing 'Use entire disk'. The crash happened immediately after selecting next on the screen.
The qcow2 image was newly-created in both the cases.
