Comment 19 for bug 29894

I'm also getting this issue in Oneiric, which I just checked out after seeing http://askubuntu.com/questions/72208/print-screen-key-doesnt-work-if-a-drop-down-menu-is-active . Interesting to note is that the Print Screen key works if menus on the top panel in GNOME Shell are open. I haven't checked to see whether this is a problem with Unity yet, though.

I also just took a look at the upstream bug out of curiosity, and I don't see any attention paid to it for over 2 years now.
