gstreamer crashes firefox when opening a menu

[jeremyhu (Jeremy Huddleston Sequoia)]

Launch firefox-x11-standalone and then click on any menu item to see this crash. Moving aside libcanberra-gstreamer.so (which calls gst_init_check) fixes the problem:

Does configuring libcanberra with '--disable-gstreamer' in place of '--disable-null' keep firefox from crashing?
If gstreamer-less libcanberra does not crash we could be absolutely certain gstreamer is the culprit. A gstreamer-less libcanberra might also provide a functioning albeit quieter firefox until a better solution is found. This seems similar to #23823 to my untrained eye - is it?

[jeremyhu (Jeremy Huddleston Sequoia)]

As mentioned, moving aside the libcanberra-gstreamer.so fixes the problem. --disable-gstreamer would do the same thing (it would not build libcanberra-gstreamer.so)

[jeremyhu (Jeremy Huddleston Sequoia)]

It is completely different than #23823

[jeremyhu (Jeremy Huddleston Sequoia)]

Actually, it's related to #23823 in that the workaround for #23823 is now causing this crash... in other words, if ${prefix}/libexec/gstreamer-0.10/gst-plugin-scanner is not present, this crash will occur.

Jeremy,
Is this problem still present?

I believe so, but I don't quite care anymore.
