+Subject: Bug 694025 - GLib drop support for adding interfaces after class_init
+
+Without this Dia crashes at startup with new GLib version and the
+DiaGdkRenderer being default. Make a new DiaGdkInteractiveRenderer which
+follows the pattern also used for DiaCairoInteraciveRenderer. This should
+be functional equivalent to what was there before and should work for all
+current GLib versions.
+
+(cherry picked from commit 213bdfe956bf8fe57c86316f68a09408fef1647e)
