ICAL crashing after opening

Question

I am having ICAL problems on my MACBOOK PRO that started after my last running of software update. Almost as soon as it opens it crashes. This does not happen on my G4. I looked in the help section of iCAL, however there was nothing that addressed this problem. In reality I only use this computer for editing and have not really noticed any issues other than the iCAL issue. Safari seems to work OK. Shortly, I plan on opening every program to see if any of them act like iCAL. Has anyone else had this problem? It is very strange!
Thanks

Had the same problem come up on my wife's laptop.
Ok, this worked for me and glad I found it before trying a complete re-install. I also verify that putting the sync server folder back in the application support folder (even when iCal was running) effectively caused iCal to crash upon the next restart of iCal.
The crash reports says:
"Exception: EXCBADACCESS(0x0001)
Codes: KERNINVALIDADDRESS (0x0001) at 0xbf7fffec
Thread 0 Crashed:
0 libSystem.B.dylib 0x900007ae5 szone_calloc+12"
and on and on...
The problems developed after I installed iTunes 7.7 to support iPhone update, etc. My wife does not use .mac however she does sync with her iPhone and uses Google spanning sync to update her calendars to Google calendars.
Moved the folder and first tried to sync her iPhone. The sync was taking longer than usual as she has no music or videos on her iPhone. After letting it sit for a while on "Syncing Contacts" I cancelled the sync.
I checked that the "Sync Services" folder was still gone from application support (i had moved and renamed it) and it was. Re-started the computer and it made another folder called "Sync Services" in the ~/library/Application Support folder but iCal worked.
YAY!
Ran the Google Spanning Sync, It did not update my test event (may have to re-install spanning sync, beyond the scope of this thread).
Ran an iPhone sync: it ran very quickly and I discovered that all of the boxes to sync contacts, calendars and such were un-checked in iTunes (not like that before). I checked them, ran a sync and BAM, iCal crashes and I'm back to square one.
DANGIT!
So, deleted the sync services folder again. Rebooted, iCal started fine. Shut down iCal and then synced the iPhone but with the options checked to "Replace information on this iPhone."
Started up iCal........no crash. Synced iPhone again (with iCal open).....no crash. Quit and re-opened iCal.....no crash. Re-booted and ran iCal....no crash.
Dare I declare it fixed?
Looks like something Hinky with the new iPhone, Apple's push to get everyone on 'Mobile Me' and the fact that i'm apparently still in the stone ages with 10.4.11.
Sorry for the length of the post. I'm more of a paramedic and writer than a techie.
