pulseaudio crashes while using vlc and crashes whole system

[Achim Behrens]

using uptodate 16.04

watching a dvb-t channels.conf with vlc (which worked in 15.10 and still works on windows with same channels.conf and vlc) crashes after some time ( <1min) and freezed whole system.

Only Sysreq reboot works.
