I think DatabaseManagerImpl is not the good place to put try/catch code. That should be part of the contract of ReportRepository, it is that last class that need to handle problem with the outer world with Box.

So, I will let that one as it is for now, because changing ReportRepository methods is rather involving, but I will trace that requirement in ticket: #2777
