Atril (evince, document viewer) default directory for Save As

Don’t ask why… A rooted Android phone or tablet can be configured to connect to an ad-hoc network, and if a separate program can configure a Linux box to act as an access point, NetworkManager should be able to do the same. As far as I can see, there are no good technical reasons for either of these deficiencies.

A system component crashing will activate the apport reporting system. What is really annoying about this is that the warning pop-up windows will keep appearing long after the problem is solved.
