[Interest] GStreamer conflicting version

[Jan Imrich]

Hello, I'm porting my project from JavaFX to Qt5 and I've encountered
following error when
QT += multimedia multimediawidgets webkit webkitwidgets
in my project file:

(Pokus:340): GLib-GObject-WARNING **: cannot register existing type
'GstObject'

(Pokus:340): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0'

I got same error using different applications on different linux platforms
(ubuntu x86, archlinux x86_64, raspbian, ArchLinux ARMv7)

I've googled and it may be caused by different gstreamer versions used by
webkit and multimedia.
Is it possible to workaround this bug? I just need quick workaround to
continue development until it will be fixed in mainline. Any help will be
really appreciated!
