I am seeing the same problem using evolution 2.6.1-3 and evolution-data-server 1.6.1-3. The error message appears to be coming from /usr/lib/evolution-data-server-1.2/camel-providers-8/libcamellocal.so which corresponds to camel/providers/local/camel-spool-store.c in the evolution-data-server source. Perhaps this bug should be reassigned to the evolution-data-server package?
The error condition is triggered because evolution prepends the string "maildir://" to service->url->path and so it doesn't begin with a '/' character. I suspect that the bug lies in the fact that a CAMEL_SPOOL_STORE_CLASS object is being created instead of a CAMEL_MAILDIR_STORE_CLASS object.
