[6.1 trunk] [crm_caldav,caldav] import error

Hello,

I tryied to update a database with latest trunk server, client and addons.

unfortunatelly, the update /launch gives a critical error on initialising crm_caldav, due to another error in module caldav (apparently a naming issue)

here is the log:
