	Another segfault occurs when choosing a custom partition
	layout, but I can't get a valid core file for that one.

	Both of these segfaults occur every time.

	This may be a ``port-pmax'' problem, and not a ``bin'' one,
	but I can only test this on a pmax now and it's an MI
	program that's causing grief.

	Boot a pmax of the diskimage from the November 8 snapshot.
	At the "select distribution" menu, choose "custom distribtion".
	Watch the distribution list appear on the screen, then the
	"Segmentation fault - core dumped" message...

	Unknown.  This is hard to debug whilst the latest sysinst
	in the 1.3 release branch isn't the same as the sysinst on
	the install tools.
