I discussed the issue with Andrea Azzarone and Martin Pitt, and the
problem might be related to the signal coming from UPower not being
reliable enough. We should really rely upon the PrepareForSleep signal
coming from org.freedesktop.login1.Manager.

We should also make sure that PrepareForSleep returns False (as this
means that the system has just resumed)

Something like the attached patch only with the "proxy_.Connect" line
changed (so as to check that PrepareForSleep returns False) should work.
