partition layout just after booting the Mageia 3 live DVD

Hi,

When a lvm volume group is on a lvm physical volume with partition type not set to 8E ('LVM Linux'), its corresponding tab is not loaded in the 'custom partitioning disk' screen next to the hard disks.

Notes:

1: It is possible to create lvm physical volumes on partitions with type 83 ('Linux'), and all lvm tools can use them as normal.

2: Fedora and Ubuntu's last install medias can use such volume groups as normal, as can the Mageia 2 install DVD.

Workaround:
Change the partition type to 8E('LVM Linux') (e.g. with fdisk).

Bug found with both the Gnome live DVD and the install DVD, x86_64, beta 2 (didn't test before this release).

I let the severity set to normal, but I don't know what to set here:
a: it blocks the installation when someone wants to install Mageia in the lvm volume group without deleting existing logical volumes,
b: but it is easy to workaround,
c: but it is easy to loose data when working around.
d: All other distros seems to support this, and Mageia did until Mageia 2.

I set the hardware to All because I think it is independent of that, but I only tested x86_64.
