I have a shared email folder "Collected" which is configured to receive messages at collected@example.org. Messages are delivery via lmtp into this mailbox. Cyrus triggers the event notification below but egara fails to compose a valid folder path ("user//Shared Folders/shared/Collected@example.org@kolab34.example.org") for metadata lookups and crashes with {F416}.
