sysinst: Segmentation fault when creating a CGD partition - MBR system

[Luis Falcon <falcon%gnuhealth.org@localhost>]

Dear all

Sysinst segfaults when trying to create partition of the type CGD
(utility menu -> partition a disk -> create partition).

From the command line everything works fine. I can create the MBR
slice, disklabel assigning the size, type and afterwards create the CGD
volume. 

I don't know if this problem is specific to MBR systems or if it also
happens in UEFI. 

PS: Computer is now happily encrypted and running, so I can't test any
further in that particular box, but if anyone is willing to do a new
install, please check if you can reproduce the error.

Best
Luis
