Antonio, please file a bug, this sounds like a system issue, not an issue in your code.

Now, since yesterday I received 6 layout constraint related exception reports (from 6 different users) with the signature shown below. I find that a bit strange, since layout constraints are not date/time based, so why would they start to appear suddenly and frequently, and not since the release of the latest version? Has anyone else started seeing similar reports over the last few days?
