I experienced the same problem signature in Natty after I installed Steam through PlayOnLinux (after logging in). I'm using the experimental FOSS 3D nVidia drivers, if that matters.

Yeah, I know... that's quite the stack of "bleeding edge/unstable" software.

I have also experienced this caused by programs running in wine

As a note, I have submitted
https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/748460
... a duplicate of this bug; my problem is in opening PDFs in evince by doubliclicking or right-clicking a PDF (that bug contains a description of my problem)

Now that unity has been under --replace, I left the PC for a while (meaning screensaver kicked in), and now, again it seems I got the freezing on double-clicking a PDF file -- but at this point, I could see the following being spit out in terminal right after the right-click failure:

----
$ ** (<unknown>:2167): DEBUG: MaximizeIfBigEnough: Evince window size doesn't fit

** (<unknown>:2167): WARNING **: Failed to fetch xid: Method "GetXid" with signature "" on interface "org.ayatana.bamf.window" doesn't exist
----

... Maybe in my case, it is ultimately a bug with Evince?
