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): 0 0x00d1a416 in __kernel_vsyscall () #1 0x007d2f25 in ppoll () from /lib/libc.so.6 #2 0x01f13e41 in gst_poll_wait () from /usr/lib/libgstreamer-0.10.so.0 #3 0x01f10ab6 in ??

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.

But that seems unlikely to be relevant, since the programs hang while starting up (apparently trying to connect to some sound server), before trying to play anything. At least, so I would think, knowing little about the sound system.
