Re: waiting for gstreamer?

This is slightly off-topic, as it is about F12, not Rawhide.
However, it's a relatively recent failure in a full-updated D12,
so it's not *too* far off-topic, I hope!

The problem is that neither amarok nor digikam nor rhythmbox
will start up. rhythmbox does nothing.  The two KDE application
(run under Gnome and metacity) will put up a splash screen, and
then hang.

In the case of digikam it looks like Phonon is waiting on gstreamer,
based on a gdb stack-trace (with digikam compiled from source):

rhythmbox also hangs in gstreamer.

One data-point which might be relevant: I briefly experimented
with xmonad (if it had a less steep learning-curve, including
better mouse support and easier defaults I might have stuck with
it).  After than the desktop icons are gone, and I can no longer
open a terminal by right-clicking the desktop (nautilus-open-terminal).
I'm not sure if the these failures predate or postdate the
xmonad experiment, but it's possible that switching to xmodad
might have done something nasty.

Do you use GStreamer codecs from RPMFusion?
