output of rhythmbox -d when UI got frozen

When I play most of the songs in my rhythmbox UI freezes and rhythmbox cannot
be controlled anymore (sound plays, but there is the window is not redrawn
anymore, so after clicking on the status bar icon the window is only grey
rectangle; right clicking on the status bar icon, doesn't give a menu).

Freezing depends on the file you try to play. There is one MP3 file which
doesn't make RB freeze, but otherwise I haven't managed to find any regularity
in what freezes and what not (both OGG and MP3 freeze).

Attaching couple of logs I generated:

* rhythmbox-*-debug.txt -- outputs of rhythmbox -d both when RB froze and when
it didn't
* rhythmbox-backtrace-* -- when the UI was frozen, I killed the process with
kill -6 and then generated backtrace from the coredump.
