Bug#850806: [pulseaudio] pulseaudio hangs in "context_autospawn"

[Bogdan Vatra]

Package: pulseaudio
Version: 9.0-5
Severity: important

--- Please enter the report below this line. ---
For some time (~1month) pulseaudio doesn't work anymore on my system (after I 
upgrade my os ~1mounth ago). Until now I just removed it because didn't had 
time to check. But today I've installed libpulse0-dbgsym and pulseaudio-dbgsym 
packages and I could trace (more or less) the problem.

As you can see it's hanged in context_autospawn, sadly I have no idea what to 
do next (besides removing it again) :). 

Yours,
BogDan.

P.S. I tried to rebuild the packages from source, but it fails to compile it.
