Any TZID is valid, because it's just a label.

> 2. which package/file/RFC contains the known/allowed TZID

We do support the Olson timezone names (see IANA) and the Windows and  
Lotus aliases, see Horde/Date.php.

> 3. is there a work around?

No.

> 4. should Kronolith catch this error?

Yes. This may happen if we come across an exception of a recurring  
event, and can find the base event, but that base event no longer is a  
recurring event. Please file a ticket.
