output of parted crash

Description of problem:
Attempting to create a gpt label on /dev/vda results core dump. Sounds like a big deal but in fact /dev/vda should not exist which may be a separate kernel bug. I discovered due to a errant "pre" section in my kickstart file referring to /dev/vda but in any case it's tickling some minor gpt bug in parted.


Version-Release number of selected component (if applicable):
parted 2.3 in Fedora 15 boot.iso (from e.g. http://ftp.osuosl.org/pub/fedora/linux/releases/15/Fedora/x86_64/os/images/ )

How reproducible:


Steps to Reproduce:
1. Boot Fedora 15 installer in a KVM virtual machine (I used virt-manager)
2. When installer starts, switch to shell (Ctrl-Alt-F2)
3. Run these commands:
dd if=/dev/urandom of=/dev/vda bs=512 count=64
parted -s /dev/vda mklabel gpt
parted -s /dev/vda unit mb print free

  
Actual results:
Core dump and errors including:
"Assertion (last_usable > first_usable) at gpt.c:713 in function _parse_header() failed.":


Expected results:
"No such file or directory" or anything other than a core dump.
