This error message just started for me yesterday, and as far as I'm aware I only did two things:
1) I tried installing enlightenment -- but because it didn't work properly I "completely" uninstalled it using Synaptic Package Manager.
2) in the same session I changed the theme of Gnome
After rebooting the computer I received this error, I have not yet tried the solutions posted above.
(BTW, I get numerous bug reports when I log on to Gnome -- so this might be a compounded problem)
