Fix for crashing iCal

[cwood]

Some users have reported iCal crashing, which can be caused by damaged
preferences files. If you experience iCal crashes, please this:

* Quit iCal
* Move these files in ~/Library/Preferences to the Trash:
- com.apple.iCal.alarmsCache.plist
- com.apple.iCal.AlarmScheduler.plist
- com.apple.iCal.helper.plist
- com.apple.Ical.plist
* Launch iCal

If that doesn't help, then the Apple Sync Services database may be
damanged. Try replacing it:

* If you haven't done so lately, make a backup of your iCal calendars
(iCal File menu > Back up iCal)
* Quit out of all open programs
* Make sure that nothing is syncing (Spanning Sync, .Mac, iSync)
* Move this folder to the trash: ~/Library/Application Support/
SyncServices
* Restart
* Open iCal and give it a few minutes to write out the new database

If the problem persists, please let us know.

Thanks,
Charlie

this process, coupled with resetting sync history allows me to use
iCal again. unfortunately that only lasts until the next time
Spanning Sync runs and syncs with Google. after that, ical is dead
again. not sure where the problem is, but it seems pretty
reproducible.

I was finally able to fix my crashing iCal after an upgrade to Leopard
by using <a href="http://buzzdroid.com/apple/mac-os-x/ical-crash-after-
leopard-upgrade-my-fix/">this method</a>. Hope it works for those who
are still having no luck with the endless crash like I was.

I'm having a different but similar problem.

iCal Helper dies continually.

I just noticed that Leopard saves each crash log in its own file
rather than making one big one for each program. Nice. Makes it
easier to get just the latest Crashlog. Also easier to tell which app
has been crashing a lot.

I should add that I have deleted the iCal stuff in
~/Library/Preferences/ and rebooted the computer, to no avail.
