The measurement tree is getting updated unnecessarily

[ivoflipse]

I'm trying to locate the cause for why my last contact isn't updated and in the process notice that the tree gets updated and updated frequently, especially when its not even visible.

I assume some of this has to do with filling the tree, so I can select the first one. But selecting a contact shouldn't have to refill the entire tree should it?

Perhaps I can check whether the tree is 'outdated' and needs updating, then set the toggle back to 'up to date'.
