I recently set up owncloud 5 and created an owncloud DAV resource using akonadi. Then I copied some contacts from my personal contacts to the new owncloud addressbook. One contact is sorted using the 'reverse name with comma' option in kaddressbook. Now, however, the name is displayed as 'surname\, name'. I tried to rename the contact using F2 but that did not work. In my owncloud addressbook no such thing occurs. The name is displayed just fine. I just tried the custom display method in kaddressbook and removed the '\' but this only works until the next sync. Reproducible: Always I am using kaddressbook 4.10.1
I cannot reproduce this bug with 4.11, closing.
