From a2977b0fe023a896c3006f27ee2b148690dff24a Mon Sep 17 00:00:00 2001
From: Jakub Filak <jfilak@redhat.com>

Subject: [PATCH] applet: switch to D-Bus methods
This patch is a part of our efforts to make abrt-applet independent on
the backend.
This patch converts all data manipulation functions to D-Bus calls, so
the notifications are made of data obtained through D-Bus.
The reporting still relies on file system access, though.
