[Bug 937933] [NEW] pulseaudio crashed with SIGSEGV (probably race in dbus library)

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Jack audio server.  Low latency kernel.  Using Ubuntu then Lubuntu via-
wubi.exe

Lubuntu was not available through wubi.exe Only ubuntu.  All other
variations produced errors.  I think needed audio packages for
multitrack recording via-Ardour and Rosegarden create unstable system
state.

Jack crashes pulse audio adapter ... rebooting seems to help sometimes.
