I have had this problem for a long time now, and it seems to me as though it does not occur unless I have connected to my computer via VNC. It seems to occur with more frequency/immediacy if I connect via VNC while the screensaver is running and the machine is locked.
The only adequate solution has been restarting X. I have just deleted the keyboard file as detailed above, so maybe that will help.
I am running 12.04 Desktop 64bit with an ATI Radeon 6670.
I have encountered this bug as described above, dbus wildly blows up and compiz eats memory while gsd churns on to no end.
.xsession-errors contained this: -CRITICAL **: app_indicator_ set_label: assertion `IS_APP_INDICATOR (self)' failed
