Resolves: rhbz#818557 crash with NULL shell post template update

It's all a bit baffling in a maze of Shells, but what I can see is that
when we update from the template at the end of loading we end up with
a different order of shells on the stack than in the usual case.
Apparently from positioning the cursor at an earlier stage than usual.

If I lock the dispatcher for the duration of updating the template it all works
out ok. I freely admit I can't foresee the full consequences of this, but it
appears to work.
