I can't believe this bug is still open. The report goes back more than 10 years.
Also the duplicate (bug 4286) mentioned above is incorrect, it points an avifile issue.
This is a incredibly high security issue that should be fixed immediately. Not only all the examples mentioned above by meany people, but the more concerning case is when you close the screen on a laptop. Even with lock screen turned on (I'm using the default gnome with Ubuntu) when you open the lid again no password is required. It makes encrypting your disk a bit pointless.

Please look into it.
