I fixed the bug. The problem was, that the function getDiagrammRect() didn't
looked at associations to find a rect around all objects. I added a function
to class AssociationWidget to return a rectangle around one association.

I also liked to take the line's width into calculation. So I'm using the
width of the association's pen. Unfortunally this allways returns a width of
0. So I have decided that a line must be at least 1 pixel in width.

Please give it a try and maybe you can solve the problem with the pen/line
width.

PS to Joerg Walter: Could you please test the code as well, because you
submitted the bug report. Unfortunally you would have to compile Umbrello by
yourself. Get the code from CVS.

PS to all: I've closed bug report #626966 (moving all objects), because no
one stood up to fight against my submitted code ;-)
