Comment 37 for bug 838792

I am encountering this bug on Ubuntu 11.10 (oneiric) and would love to help diagnose/fix this issue. I'm not well versed in the parts of the system that are invoked when the "shutdown" button is selected, but can offer the following data points about my configuration:

* Running under VMWare Player 4.0.2 build 591240
* did not experience the issue after initial install and subsequent updates
* began experiencing the issue after installing Chef and its dependencies (via instructions at http://wiki.opscode.com/display/chef/Installing+Chef+Server+on+Debian+or+Ubuntu+using+Packages)
* noted that RabbitMQ is a key Chef dependency, and highlighted in other comments, so may be suspect
* wondered if it may be Lightdm/session related and affected by https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/933626 or similar

This seems like a fairly big haystack to me, but happy to post any debugging output that might be valuable.
