  I've already found problems mixing gstreamer versions, To keep on the safe 
side I'd always bet for not mixing them. I haven't comprehensively analysed 
implication though.

  My idea would be disabling phonon (and gstreamer) dependency from the qt-x11 
build. The only binary that's related to phonon (and gstreamer) is libqt4-
phonon which provides:
  * phonon solibs (already provided by libphonon4 package). Moreover the 
phonon libs that can be found in libqt4-phonon corresponds to an old phonon 
version 4.4.0 vs current 4.7.2 in libphonon4 package
  * phonon designed plugin. I'm not sure what's this for, but if it's related 
to qtconfig somehow I can say that here qtconfig provides a phonon tab 
(detecting libphonon4 phonon version and gstreamer 0.10!! [1] )

[1] I'm running self build debian package for 4.8.3 phonon-backend-gstreamer

  Also libphonon4 conflicts with libqt4-phonon.

  If you would like to go this path I can offer the patch (attached) I'm trying 
to use to build qt4-x11. I have failed to build it so far due to problems on 
my machine. Patch should apply cleanly to current debian qt4-x11 git HEAD.

  Please, let me know how else I can help. Regards
