That sounds like it will work, but doesn't seem a very elegant solution. 
 In addition, when I zoomed in as close as I could then tried to 
further minimise the ellipse Dia crashed on my repeatedly (0.94, 
installed via apt on Ubuntu)

I see 2 options here:

1) allow the creation of arbitrary zero size connection points which can 
be added to the diagram for this purpose

2) Allow the end of a line to act as a connection point.
