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.

Errr...

'impossible to port to GSTreamer 1.0'...

well, if we switch libcanberre to gst 0.10, all the other apps will break.. GST 0.10 is no longer maintained, so that sounds like a terrible trade off.

As such, the best thing for now is likely to modify /etc/X11/xinit/xinitrc.d/libcanberra-gtk-module.sh

and not have canberra-gtk-module added to GTK_MODULES.

This though should ONLY happen on XFCE imho (what's the best way to identify if the session running is XFCE?)

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.

...

Will it select the backend at runtime based on what is available? This could probably also solve the issue with Firefox noted on the factory list which uses libcanberra directly.

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).

I just checked with a VM containing the Xfce default install, at least the GTK module will load all backends by default: $ leafpad & $ awk '/asound|gstreamer|canberra/ { print $6 }' /proc/$(pidof leafpad)/maps | sort | uniq /usr/lib64/gtk-2.0/modules/libcanberra-gtk-module.so /usr/lib64/libasound.so.2.0.0 /usr/lib64/libcanberra-0.30/libcanberra-alsa.so /usr/lib64/libcanberra-0.30/libcanberra-gstreamer.so /usr/lib64/libcanberra-0.30/libcanberra-multi.so /usr/lib64/libcanberra-0.30/libcanberra-oss.so /usr/lib64/libcanberra-gtk.so.0.1.9 /usr/lib64/libcanberra.so.0.2.5 /usr/lib64/libgstreamer-1.0.so.0.5.0 $ kill $! ... $ unset GTK_MODULES $ leafpad & $ awk '/asound|gstreamer|canberra/ { print $6 }' /proc/$(pidof leafpad)/maps | sort | uniq $ -- 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.
