While looking at bug 44397, https://bugs.freedesktop.org/show_bug.cgi?id=44397 Gnome's volume control somehow wanted to create a filter sink cycle. I'm attaching a patch to prevent this, which seems to have worked (at least there is no crash!), but before I push it: Is there any reason, any use case, where we actually would want a cycle? I can't think of any, but just wanted another thought in case I missed anything. -- David Henningsson, Canonical Ltd. http://launchpad.net/~diwic
