Title:

Bug description:
qtmultimedia plugins like libgstcamerabin.so or libgstmediaplayer.so link
against gstreamer-0.10:
ldd /usr/lib/x86_64-linux-gnu/qt5/plugins/mediaservice/libgstcamerabin.so
[....]
libgstinterfaces-0.10.so.0 =>
/usr/lib/x86_64-linux-gnu/libgstinterfaces-0.10.so.0 (0x00007fa8e4fdb000)
libgstpbutils-0.10.so.0 =>
/usr/lib/x86_64-linux-gnu/libgstpbutils-0.10.so.0 (0x00007fa8e4db6000)
libgstreamer-0.10.so.0 =>
/usr/lib/x86_64-linux-gnu/libgstreamer-0.10.so.0 (0x00007fa8e4acc000)
while UbuntuComponents links against gstreamer-1.0:
ldd /usr/lib/x86_64-linux-gnu/qt5/qml/Ubuntu/Components/libUbuntuComponents.so
[...]
libgstvideo-1.0.so.0 => /usr/lib/x86_64-linux-gnu/libgstvideo-1.0.so.0
(0x00007f65a3e9f000)
This seems to cause an initialization problem of gst-0.10:
(camera-app:6221): GLib-GObject-WARNING **: cannot register existing type
'GstFormat'
(camera-app:6221): GLib-CRITICAL **: g_once_init_leave: assertion
'result != 0' failed
(camera-app:6221): GLib-GObject-WARNING **: cannot retrieve class for
invalid (unclassed) type '<invalid>'
(camera-app:6221): GLib-GObject-WARNING **: cannot register existing
type 'GstQuery'

(camera-app:6221): GLib-GObject-WARNING **: cannot retrieve class for

And that in turn makes the main thread of the application block
indefinitely
