I made a small one on a boot stick, moved it to a VM with CentOS 6.2 running, 
and cannot reproduce the problem. In fact, parted sees the core storage 
enclosed logical volume's name, even though it doesn't identify the file system 
being used.

I inserted another boot stick, that contains an 'Apple boot' partition with a 
minimum system. This is also new in Lion and is actually used as the initial 
boot partition only when the primary partition has been encrypted. When that's 
inserted, the problem is reproducible - parted crashes only upon trying to list 
the contents of that USB stick (it lists the contents for sda just fine).

The problem though, with assuming it's the Apple Boot partition, is that I had 
this working fine two months ago with such an Apple boot (this is GUID 
426F6F74-0000-11AA-AA11-00306543ECAC). So either some Apple update has messed 
with this partition in some way since then, or I did (entirely possible).

So even if I've somehow sabotaged either of the two 620MB Apple Boot partition 
examples I have that cause this problem, I'm thinking it might be useful to 
find out why parted is crashing because it probably shouldn't crash. Even 
though this is pretty obscure. Maybe?

In any event, I need to do a clean install of Lion again, and see if a totally 
unmodified version of it causes the problem; and if and which update instigates 
the problem.
