Could you try the attached patch? Zoiper seems to test all the available
sources and sinks if I read the log right. So module-filter-apply at some point
tried to use the monitor source of the echo-cancel sink as source for the
filter.

Yes, this patch solves the segfault.

Nice! I googled "filter.apply.echo-cancel.parameters" with no results. Can you
provide an example of its use or a docs or code reference?
