Bug Description
This is a breakaway bug from bug 1351308.
accountsservice 0.6.37-1ubuntu7 introduced a new bug where libaccountsservice would not report the manager object as loaded. It wasn't because of the content of that upload, but rather seemingly because of building with a new compiler. It got uploaded shortly after the gcc 4.9 transition.
I wasn't able to determine whether this is something accountsservice is doing or just gcc's fault. But even inserting some debug statements around the place or downgrading optimization to -O1 made the problem go away. So I'm leaning towards gcc.
For now, we just changed optimization in the package to workaround the problem. But the root source should be investigated.

Doko, you asked me to re-test if this is still a problem. It is. :( I rebuilt accountsservice with latest utopic and without the optimization work-arounds I had put it in it before. Still hit bug 1351308.
