Thanks for the analysis. Please try what I just committed.

I have a problem when I try to synchronize the calendar of my SE W880i.



If I add some calendar entries in the kronolith calendar, I am able to 
synchronize the calendar with my phone, but if I add/modify an entry 
in my phone calendar and try to synchronize that the phone reports 
"illegal answer from server" and the following lines are printed in 
the php error log.



[26-aug-2007 10:55:08] PHP Fatal error:  Call to undefined method

PEAR_Error::getUID() in /horde/kronolith/lib/Driver/sql.php on line 630



In the Horde log I have found the log output from the Kronolith delete 
method where the PEAR_error occur. From the log output it seems like 
the value of

"$this->_calendar" is set to a wrong calendar id, in this case an other user's

calendar(userB@example.com), and therefore "getEvent" returns a 
invalid event. The event_id is ok for the given "user" value.

As a temporary hack, I have added this line 
"$this->_calendar=Auth::getAuth();" to the

function "getEvent" in Kronolith/lib/Driver/sql.php, and this seems to 
solve the issue.
