Google Cal Sync duplication, help...

My google calendar sync has been working well on and off for some time, however since my last os upgrade (from 4.2.2.66 to 4.2.2.176) I've had consistent issues whereby google calendars is duplicating calendars. I never get more than 2 of everything, but I DO allways now end up with two of everything.

Any suggestions or fixes.

As a note, I don't believe I've installed the calendar patch since the upgrade, would that be it? Last time (when I had .66) it wouldn't even run w/o the patch.
