Subject:	[geda-user] crash connecting to nets

Encountered a crash trying to connect nets on a hierarchical
schematic. Looking at the stack trace, trying to figure it out
s_conn.c:407 - (in s_conn_update_line_object)

407          if (object->line->x[j] == other_object->line->x[k] &&
408	              object->line->y[j] == other_object->line->y[k] &&
409	              check_direct_compat (object, other_object)) {
...

it appears that other_object->line is null, trying to connect to a pin
on the symbol I created for one of my sub schematics. It seems to
happen when I make a two part connection between two nodes. In other
words, I start the net at Sub Comp A, pin 1, and stop it somewhere
short of connection to Sub Comp B, pin 1. Then I come back and connect
to the net I just drew, to Sub Comp B, pin 1 and BAM!.   What's
interesting is that I can make the connection the other way around
(from the pin to the existing net line).

in this case object->type is OBJ_NET, and other_object->type is 198
(which doesn't appear to map to any known object type that I found in
o_types.h).

What is object->type == 198, and does there need to be a special case
in s_conn_update_line_object for other_object->type ==
SOMETHING_OTHER_THAN_PIN_OR_LINE?
