Relevant IRC bits from #plasma yesterday:
> <einar77_work>	sitter: I think phonon and PA 7 are going crashy crashy - https://bugzilla.opensuse.org/attachment.cgi?id=651707
> <sitter>	einar77_work: did PA change structs again?
> <sitter>	einar77_work: I am reasonably certain that is either a BIC in libpulse or a random bug. the phonon side is pretty straight forward
> <einar77_work>	sitter: it's triggered apparently with a PA module that's now on by default
> <einar77_work>	sitter: and it crashes kmix's kded too, so I think it's a PA issue

I am not sure einar77 forwarded the bug to the pulseaudio guys, so CCing him.

It's currently tracked downstream at http://bugzilla.opensuse.org/
show_bug.cgi?id=950487.
Comment 3 Luca Beltrame 2015-10-16 05:42:07 UTC 
Workaround: edit your /etc/pulse/default.pa configuration, locate the line that says

load-module module-native-protocol-unix 

and change it to

load-module module-native-protocol-unix srbchannel=no

Since the reporter is an openSUSE Leap user, I can confirm it's the same issue (hit automated tests too).
Comment 4 Christoph Feck 2015-10-20 11:08:27 UTC 
https://bugzilla.opensuse.org/show_bug.cgi?id=950487 says the bug is fixed in openSUSE pulseaudio packages.
