parted offers existing encrypted PVs when making new VG

[Chuck Anderson <cra WPI EDU>]

anaconda-11.4.1.58

I have sda5 encrypted PV with an existing VG on it.  I want to create 
a new VG to install to, so I select a free partition and click LVM.  
In the list of Physical Volumes to Use, sda5 is checked off by 
default, along with the new blank partition I want to use.  This is 
dangerous, because the user might unknowingly overwrite an existing 
encrypted partition.

This happens only when I enter the passphrase to unlock sda5.  If I 
don't enter the passphrase for sda5, I'm not offered that partition as 
a choice for creating the new VG.

Should I open a bug on this?  Is this F10 blocker material?
