I dug into the sources myself and it looks to me that there is
no simple solution for this problem.
I found out that pins which are created by the net= attribute simply
cannot have any other attribute (they are not there as an OBJECT).
One fix could be, to supply a default value for the pintype attribute
for these pins in g_netlist.c, like the following change in
g_get_attribute_by_pinnumber() would do:
--- g_netlist.c.orig 2006-01-16 14:17:56.000000000 +0100
+++ g_netlist.c 2006-02-26 22:08:39.000000000 +0100

}
}
}
nl_current = nl_current->next;
}
The change feels like a hack, though. Is there a better solution?
Best,
Holger.
