Portable iCal

System crash *.pabu restore

Portable iCal create a temporary back-up of ~/Library/Application Support/iCal, ~/Library/Caches/iCal, ~/Library/Preferences/com.apple.iCal.plist, com.apple.iCal.AlarmScheduler.plist and com.apple.iCal.helper.plist (named *.pabu) that are restored when application is closed. If a system crash occurred Portable iCal will not restore local iCal preferences and temporary back-up still exist.
Note that a crash of iCal application will allow Portable iCal to restore local preferences.

To fix this, a temporary hidden app that restore *.pabu file and folders is copied on local home directory (~/.Portable_iCal_scr.app) and is opened at login by launchd agent after a system crash. This temporary application is deleted when restore process end with success.
If some *.pabu still exist, when you reopen Portable iCal you can Restore or Copy temporary back-up.
