Sunbird Calendar Broken

[Jonathan Ryshpan]

I have just installed the latest sunbird, namely
	sunbird-1.0-0.11.20090715hg.fc11.x86_64
When started, it shows two error boxes and no calendar information.  
The error boxes read:

Box 1:
        An error was encountered preparing the calendar located at
        moz-profile-calendar://?id=2 for use. It will not be available.
        
        [Exception... "Component returned failure code: 0x80004005
        (NS_ERROR_FAILURE) [mozIStorageStatement.reset]"  nsresult:
        "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame ::
        file:///usr/lib64/sunbird-1.0pre/modules/calStorageUpgrade.jsm :: ensureUpdatedTimezones :: line 380"  data: no]

Box 2:
        An error was encountered preparing the calendar located at
        moz-profile-calendar:// for use. It will not be available.
        
        [Exception... "Component returned failure code: 0x80004005
        (NS_ERROR_FAILURE) [mozIStorageStatement.reset]"  nsresult:
        "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame ::
        file:///usr/lib64/sunbird-1.0pre/modules/calStorageUpgrade.jsm :: ensureUpdatedTimezones :: line 380"  data: no]
        
I presume that these two errors refer to the two calendars entered into
sunbird.

Has anyone seen these two errors?  What's the easiest way to install the
preceding version of sunbird?

Thanks - jon
