Public bug reported:

Binary package hint: pulseaudio

On a fresh Karmic Alpha 5 desktop, I had gnome-terminal and firefox
windows open, no flash player installed and no audio running when a
notification popped up about pulseaudio crashing on an assertion failure
but apport is not configured to report about.

[karmic] pulseaudio crashes on an assertion failure
https://bugs.launchpad.net/bugs/425028
You received this bug notification because you are a member of Ubuntu
Audio Team, which is subscribed to pulseaudio in ubuntu.

At first I thought the PPA version was the answer, as audio was working and no more assertion failures were being announced.

However, without running any audio apps (but I did enable system sounds in order to verify that audio was working), in fact the only app I have open is gnome-terminal but not even running any command except top or htop, pulseaudio consumes between 46-57% CPU as reported by top and 70-100% as reported by htop.

This results in a system where the mouse pointer moves in real time with my actions, but apps and every other aspect of the desktop UE are very slow to respond, including mouse clicks.

Forgot to mention which version was picked from the PPA:
