Public bug reported:

SRU
-----

[Impact]
Every Phonon enabled application that uses subtitles (namely most KDE video players) can crash when gstreamer returns a null ptr as cstring. This is addressed by simply checking for null.

[Test Case]
* Try to play http://meta.metaebene.me/media/raumzeit/rz040-goce.m4a in dragon player
* Observe dragon crashing

[Regression Potential]
* none

------

The Phonon GStreamer subtitle code crashes when gstreamer returns null
ptrs to tag queries where phonon expects a valid string.
