Comment 3 for bug 476505

Yes, as you can see in the attached file (modified.conffile..etc.default.pulseaudio.txt), pulseaudio was set to start in system mode (I have changed this setting back to the default). I don't remember why I set this option, but it was probably an attempt work around some problem I was having with pulseaudio in 9.04.

Even if this configuration is not recommended, the suspend scripts should be robust enough to handle it (or else this configuration should not be possible).
