How do I determine which calendar entry is breaking my Android calendar sync? First a bit of background for those who aren't familiar: Just a few weeks ago Samsung released their ICS build of TouchWiz, and my phone (a Samsung Galaxy SII) updated over the air. Ever since none of my calendars have synced. It turns out there's a bug wherein recurring events that were present before the update (I think it's only them?) can cause calendars to stop syncing. (I've searched in vain for a concise link to the problem to reference... )

I've tried factory resetting to no avail and I've tried deleting all my extraneous calendars and the recurring events I could find, but sync still doesn't want to work. Is there any way that I can track down which events are causing the trouble more precisely?
I know it's typically frowned upon to answer your own question, but I have. This was a total PEBKAC. I use a different calendar app than the default, so I disabled the pre-installed Samsung calendar in the Application settings in order to stop it appearing in my application list. This is fine and doesn't affect anything, but I apparently got a little trigger happy and also quite stupidly disabled the Calendar Storage process. Yeah, that'll mess up calendar sync something fierce.
