gEDA-dev: gschem: Crash deleting attributes

[Peter Clifton]

Hi all,

It appears the git HEAD code crashes deleting attributes from nets. I'm
can't recall if this is in 1.4.0 or not, but either way it needs fixing.
We shouldn't call o_attrib_slot_update() for non-complex objects.

Its related to slot updates:

Program received signal SIGSEGV, Segmentation fault.

1590      o_current = object->complex->prim_objs;

(gdb) print object->complex
$2 = (COMPLEX *) 0x0

(It is a net, not a complex!)
