The file included an nSKEL object:

= nSKEL
5 4 10

0 0 0 0
1 0 0 0
0 1 0 0
0 0 1 0
0 0 0 1

2	0 1 	1 0 0 1
2	0 2 	0 1 0 1
2	0 3 	0 0 1 1
2	0 4 	1 1 1 1

The "5 4 10" would mean it lives in 5-space, contains 4 vertices and
10 polylines.  But actually it lives in 4-space, contains 5 points
and only 4 polylines.  So the header should read:

nSKEL
4  5 4

..

Of course it shouldn't have *crashed* after reporting "expected vertex count
on polyline 4 of 10".  I'll fix that.
