 When trying to resume a large file (Journal backup bundle, ~400MB) from a
 mounted volume (internal hard disk), a dbus timeout happens. No user
 feedback is given even though the fix for #1842 has been merged.

 dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Did not
 receive a reply. Possible causes include: the remote application did not
 send a reply, the message bus security policy blocked the reply, the reply
 timeout expired, or the network connection was broken.

 The data store call only returns after the entry has been successfully
 stored, so we need to increase the DBus timeout.
 This happened with the version support branch, but mainline doesn't set
 dbus timeouts either so will have the same issue.
