https://bugzilla.redhat.com/show_bug.cgi?id=947640 --- Comment #11 from Antonio Trande <anto.trande@xxxxxxxxx> --- There is a malfunctioning in snappy, it's documented by this warnings: (snappy:27349): GLib-GObject-WARNING **: specified class size for type `ClutterGstVideoSink' is smaller than the parent type's `GstBaseSink' class size (snappy:27349): GLib-GObject-WARNING **: cannot register existing type `GstObject' (snappy:27349): GLib-CRITICAL **: g_once_init_leave: assertion `result != 0' failed (snappy:27349): GLib-GObject-CRITICAL **: g_type_register_static: assertion `parent_type > 0' failed (snappy:27349): GLib-CRITICAL **: g_once_init_leave: assertion `result != 0' failed (snappy:27349): GLib-GObject-WARNING **: interface type `GstImplementsInterface' or prerequisite type `<invalid>' invalid (snappy:27349): GLib-GObject-CRITICAL **: g_type_add_interface_static: assertion `G_TYPE_IS_INSTANTIATABLE (instance_type)' failed (snappy:27349): GLib-GObject-CRITICAL **: g_type_add_interface_static: assertion `G_TYPE_IS_INSTANTIATABLE (instance_type)' failed (snappy:27349): GLib-CRITICAL **: g_once_init_leave: assertion `result != 0' failed (snappy:27349): GStreamer-CRITICAL **: gst_element_register: assertion `g_type_is_a (type, GST_TYPE_ELEMENT)' failed This problem seems caused by a conflict between gstreamer and gstreamer1 if installed together. snappy needs 'gstreamer1' but 'gstreamer-old' is required by 'clutter-gst' that it is another required package. So I changed 'clutter-gst' in 'clutter-gst2' (snappy requires clutter-gst >= 1.5.5) and conformed the .spec file to find the right header/libs files. The warnings are disappeared and snappy works better. I inform the upstream in order to know if this change is acceptable. I'm sorry, Mario. I have just checked about this issue. -- You are receiving this mail because: You are on the CC list for the bug.
