So basically every GTK application which links against libgstreamer-0.10 will blow up because the libcanberra gtk module brings libgstreamer-1.0 into the same process space.

Two solutions:
- Don't link gstreamer into xfce-mixer (why would the mixer need this anyway?)
It is build on the GstMixer API which is a cross-platform abstraction of different audio mixer interfaces.
- Port xfce-mixer to GStreamer 1.0 (in most cases the port is rather simple)
Upstream was so nice to remove the above API without warning before the 1.0 release (http://cgit.freedesktop.org/gstreamer/gst-plugins-base/commit/gst-libs/gst?i...) so that is simply impossible. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

There isn't really, when /etc/X11/xinit/xinitrc.d/ gets called xfce4-session isn't running yet and environment variables like GDMSESSION or DESKTOP_SESSION are only set by GDM and LightDM. You can e.g. also run xfce4-mixer in LXDE or with Openbox so this doesn't look like a viable solution. This problem is not also specific to the xfce4-mixer panel plugin, it affects any application linking to both GTK and libgstreamer-0.10 which are probably a lot. Only on my Factory Xfce installation this affects firefox, shotwell, and rhythmbox which all have libgstreamer-1.0 and libgstreamer-0.10 in the same process space and libgstreamer does not use symbol versioning. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It would be much better to just drop gstreamer backend in libcanberra. It already supports Pulseaudio and Alsa and Fedora has disabled gstreamer backend in their package for almost one year, without any issue.
Will it select the backend at runtime based on what is available?

Yes, libcanberra will try the various various, in the following order : #ifdef HAVE_PULSE "pulse", #endif #ifdef HAVE_ALSA "alsa", #endif #ifdef HAVE_OSS "oss", #endif #ifdef HAVE_GSTREAMER "gstreamer", #endif so, in our case, gstreamer was probably never case (we build libcanberra with pulse and alsa backend and not oss one). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
