/*
* Outstanding bugs
* 1) When adding a contact to an empty addressbook from the pop-up menu
* when right-clicking on an email address causes claws-mail to crash in
* addritem.c line 965. Severity: Show stopper. Solved in 2.9.2cvs17
* 2) Updating a contact gets lost if the user makes a new search on the
* same LdapServer. Severity: Medium. Solved in 2.9.2cvs17 (patch added to solve 1) also solved this bug)
* 3) After adding a new contact the displayName for the contact is empty
* until the user makes a reread from the LdapServer. Severity: minor.
* Solved in 2.9.2cvs24
