	I get the following gdb output:

>How-To-Repeat:
	This is the disklabel (I got it from the disk):

# /dev/rsd7c:
type: SCSI
disk: SCSI disk
label: fictitious
flags:
bytes/sector: 512
sectors/track: 52
tracks/cylinder: 15
sectors/cylinder: 780
cylinders: 1632
total sectors: 1295850
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0		# milliseconds
track-to-track seek: 0	# milliseconds
drivedata: 0 

8 partitions:
#        size   offset    fstype   [fsize bsize   cpg]
  a:  1295850         0    4.2BSD        0     0       	# (Cyl.    0 - 688296*)
  c:  1295850         0
  g:  1295850         0    4.2BSD

>Fix:
	I have not looked at it yet.  I'm still trying to see if
changing the label itself will fix the problem.

 I suspect this is caused because you don't specify an fstype for
 partition c.  

 I have just committed changes which might fix this problem.  They're not
 suppable at this point, but if you would like to test them out I can
 mail you a new disklabel.c to drop in.  

 I get this as output from running disklabel on the sample you
 submitted:

 disklabel: line 22: warning, unknown filesystem type: (empty)
 disklabel: line 22: too few fields
 disklabel: line 23: too few fields
