Comment 5 for bug 758839

I tested by reverting the lazy loading branch of unity and they all worked fine. So it was introduced by rev 1133 on trunk.

Without reverting that branch, I do see the following output in .xsession-errors when right-clicking on a lens that isn't loading the sections:

(<unknown>:24978): dee-CRITICAL **: dee_model_get_first_iter: assertion `DEE_IS_MODEL (self)' failed
(<unknown>:24978): dee-CRITICAL **: dee_model_get_last_iter: assertion `DEE_IS_MODEL (self)' failed

I suspect it isn't really lazy loading the sections model, so now it doesn't block on the model being up but never connects when it is available.
