[kronolith] Thunderbird Lightning does not display Kronolith Calendar events

[Ferdinand Gruber]

May be after updating horde groupware, anyway, now I don't see any 
calendar events in Thunderbird Lightning.
Don't know if it is caused by Lightning or by Horde.

In the Thunderbird error console I can see 2 may be relating messages:

    CalDAV: Fatal Error parsing etags for MyHordeCalendar
    NS_ERROR_UNEXPECTED: Component returned failure code: 0x8000ffff 
(NS_ERROR_UNEXPECTED) [nsISAXXMLReader.onDataAvailable]

Please help!
