After resuming from sleep sometimes the computer goes to sleep again

[Simon Strandman]

When I close the lid on my laptop the system is configured to suspend, but sometimes when I open the lid there is just enough time for me to enter the screensaver password and see the desktop before the computer suspends again.

This does not always happens, most often it just wakes up as it should. I'm not sure whats triggering this bug.

There are other bugs about similar issues, such as #425411 and #306310, but they are marked as fixed and this is still happening on a up to date natty system (with proposed updates enabled).

This is getting weirder. I can get the computer to enter sleep mode by disconnecting the power if I do it this way:
1. Disconnect the power.
2. Put the computer to sleep by closing the lid.
3. Reconnect the power while the computer is sleeping.
4. Wake the computer by opening the lid.
5. Disconnect the power again.

The moment I do step 5 the computer goes to sleep again. This is 100% reproducible.
