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