Comment 12 for bug 321311

Using gtk-2.0 2.15.5 this bug still exists. And others are also still experiencing the problem since it is continuing to appear on the development forums.

Interesting side note, the password will be accepted and the screen will become unlocked however the screensaver will not give up focus to anything else. I hit Alt+F1 for the menu keyboard combo and was able to access it fine and Alt+F2 allowed me to run an application, however they all ran behind the screen saver.
