Backtrace from crash

After emerging tomahawk-0.8.2, I tried to play some audio.  It immediately crashed, so I generated a backtrace (attached) and emailed the developers.  I received the following reply:

So I removed media-libs/phonon-gstreamer (as well as the "gstreamer" flag on media-libs/phonon) and installed media-libs/phonon-vlc.  I could then play audio.  It seems that from this experience, the ebuild is missing a dependency and possibly a blocker.

Did they say why they think phonon-gstreamer is broken in Gentoo? It seems unlikely this is a tomahawk-specific issue.

No, that was the extent of the reply unfortunately.  Perhaps I could ask for more info.

Which version of phonon-gstreamer do you have at least?

4.8.2.

This looks like bug #522880, where phonon-gstreamer-4.8.2 uses gstreamer-1.0, while qtwebkit uses gstreamer-0.10 which causes a symbol collision. If this is the case, it work by downgrading to phonon-gstreamer-4.7.2

I reinstalled phonon-gstreamer-4.8.2 and could not play audio with tomahawk.  I then downgraded to phonon-gstreamer-4.7.2 and can play audio with tomahawk.
It looks like Michael's at least on to something here.

There's an update qtwebkit package which may solve this issue: https://github.com/gentoo/qt/tree/master/dev-qt/qtwebkit23
