I have been trying to print labels from Writer using my evolution address book,
which uses the evolution-data-server webdav backend. However, tables in the
webdav backend aren't visible in evolution; only the file, ldap and groupwise
backends are visible. Also, the recently introduced couchdb backend is not
visible in OOo.

Assuming the e-d-s provides the same view onto its webdav and couchdb backends,
the old patch here:

http://www.openoffice.org/issues/showattachment.cgi?attach_id=34220

suggests that it would be fairly simple to modify this file:

http://dba.openoffice.org/source/browse/*checkout*/dba/dbaccess/source/ui/dlg/dbwizsetup.cxx?rev=1.35

and possibly some other files, so as to include the webdav and couchdb backends.

Would this be fairly straightforward? I would have a go at a patch myself, but I
don't have time to get to grips with the build process at the moment.

All the best,

David
