It looks like /etc/init.d/pulseaudio is corrupted. This is the same issue you reported in bug 529463. It is not a bug with the package but with your system being corrupted. Could you please ask a support channel a support channel (#ubuntu or an ubuntu forum) how to recover from this error. Thanks

Thank you for taking the time to report this issue and helping to make Ubuntu better. Examining the information you have given us, this does not appear to be a bug report so we are closing it and converting it to a question in the support tracker. We appreciate the difficulties you are facing, but it would make more sense to raise problems you are having in the support tracker at https://answers.launchpad.net/ubuntu if you are uncertain if they are bugs. For help on reporting bugs, see https://help.ubuntu.com/community/ReportingBugs#When%20not%20to%20file%20a%20bug.

Here is my file from Lucid if it helps:

You could always boot to a karmic live CD and copy the file from there too if the one I gave dowsnt work. Even though your file is bad, back it up
