Summary:
My MBP had been running nicely for multiple days. It had been into sleep mode multiple times without any problems. It also successfully entered sleep mode when connected to a FW800 HD, a Wireless Apple Keyboard (BlueTooth), an external monitor and a USB hub to which a mouse and my iPhone were connected.
But then I wanted to put my MBP into sleep mode once more, and it simply wouldn't. I tried about 10 times. Then I disabled "allow BT devices to wake up my computer". No difference. Then I disconnected the FW800 HD, the screen and the USB hub. I.e. everything. The problem persisted.
I had to shut down my MBP.
Movie attached. The sound quality isn't great, but you can clearly hear the typical (annoying!) noise of the DVD drive when upon booting, it checks if it has a disc it should pull in.

Steps to Reproduce:
Unknown.

Expected Results:
A MBP that is able/willing to enter sleep mode at all times.

Actual Results:
A MBP that in rare cases won't enter sleep mode.

Regression:
This never happened in OS X 10.5.
