I made a local 'pa auwx' dump at the same time, in case more information is required.

I'm using the following indicators:
/usr/lib/indicator-messages/indicator-messages-service
/usr/lib/indicator-session/indicator-session-service
/usr/lib/indicator-sound/indicator-sound-service
/usr/lib/indicator-application/indicator-application-service
/usr/lib/indicator-datetime/indicator-datetime-service

I also have system-monitor indicator which displays current CPU and RAM resource allocation on the gnome panel and updates in a 5 second interval.
indicator-datetime displays hours, minutes as well as seconds (I've read smoewhere this can cause trouble with DBUS).

ps isn't a terribly informative source; could you profile it with valgrind? (If not, I probably could, but perhaps not till this weekend.)

[Moritz Naumann (mnaumann)]

Thanks Thomas, can you provide me with instructions on how to profile?
I assume I'd want something along the lines of this?
valgrind --tool=memcheck -- compiz --replace
I tried it but it - logically - removed the link between unity and compiz, so I needed to also run unity --replace to get things going again.

[Daniel Nyström (speakman)]

I'm also having massive memory leaks with compiz. If someone could put some instructions how to profile I'd be glad to help.

That version has reached EOL since a while, so it will not receive update. If that issue still exist, report again using ubuntu-bug.
