            Bug ID: 755754
           Summary: videoaggregator doesn't compile with in openembedded
                    dora (glib 2.36.4)
    Classification: Platform
           Product: GStreamer
           Version: 1.6.0
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad

hey Thiago, i discovered that the patch 
http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/commit/gst-libs/gst/video/gstvideoaggregator.c?id=ba97ec74bedd3d8e910052d8345becc42ad75813
break crosscompilation of gst-plugins-bad 1.6.0 in our openembedded dora
environment. it probably happens in any environment using glib 2.36.4 and gcc
4.8.1, i haven't tested that.
it seems the use of the glib private macro _G_DEFINE_TYPE_EXTENDED_CLASS_INIT
is causing the build error
