Bug Description
[Impact]
In 4.6.2 when gstreamer cannot be initialized successfully (broken cache for example) or phonon-gstreamer's runtime requirements are not met, it will still try to create objects with appropriate validity values. However those objects are not appropriately validated in every function, such that at some alter time a phonon-gstreamer based application will crash for no apparent reason.
This is easily overcome by simply relying on the already present validation system in libphonon, to do that phonon-gstreamer simply must not return objects (return 0).
[Test Case]
Forcefully uninstall all gstreamer plugins and try to play a video with dragon player. It should crash.
[Regression Potential]
None. If gst could not be initalized phonon gstreamer would not have worked at all, this remains the same, except now it cannot crash when accessing uninitalized pipeline parts etc.
