Julien found this deadlock:
> On master only (I don't have the problem on 3.5 branch), Base hangs when I

i can reproduce this on current master from yesterday,
master 8829b7c9, master 46506f82, but not master 904d59fa or libreoffice-3-5.
so it looks like a recent regression.
the proposed patch by mmeeks probably does not fix the problem,
because the SolarMutex is locked some more up the stack of the main thread:
> void SAL_CALL OGenericUnoController::dispose()
> throw(::com::sun::star::uno::RuntimeException)
> {
> SolarMutexGuard aSolarGuard;
> OGenericUnoController_Base::dispose();
> }

i'd guess the deadlock was caused by this commit, which introduced the
+ m_pEventBroadcaster->join();
