>Description:
While setting up a CGD partition, the installer segmentation faults after selecting the partition and choosing the "Encrypt" menu option. This occurs on both GPT and MBR partitioned disks.
>How-To-Repeat:
Quickest way:
Start sysinst
Enter the Utility Menu
Partition A Disk
Choose the hard drive.
Partition as GPT, create a partition. The type doesn't matter.
Accept the partitioning
Select the newly created partition in the extended partitioning menu
Select "encrypt"
The installer segfaults.
>Fix:
No fix, but a workaround:
Running cgdconfig commands manually works fine.

 I think the confusion is about calling pm_cgd_edit_old (wrong in this case)
 and pm_cgd_edit_new (to convert the selected partition into a cgd device
 first time).
