Focussing script crashes

This script crashes randomly with segmentation fault

This seems to be something to do with the 'python arrow' - apparently it goes away if that's disabled.

Here's the backtrace:

Moved as part of iteration 18 end

[Martyn Gigg]

(In [2928]) The algorithm dock widget was being updated whenver a workspace was replaced or deleted which was causing crashes for me. It was also adding unecessary work. Re #657

Fix went in a long time ago. No complaints received recently.
