Ok so it's indeed the same problem. And from that came the realization of 
the fundamental difference between apt-get vs apt-shell and synaptic:
in apt-get the update step is a separate program launch, whereas apt-shell 
and synaptic continue the session .. this makes the problem go away:

That probably leaves us with a slight memory leak, but even that is better
than segfaulting :)
