[Bug 47919] Re: kontact / kadressbook creates duplicate contacts

[Geoff Hoff]

I found the problem.  The k/ubuntu kdepim source package applies the
patch named kubuntu_09_kmail_addressbook.diff.  This was necessary in
kdepim-3.5.1 per this bug http://bugs.kde.org/121337 because kmail
wasn't displaying address book entries.  This was fixed in 3.5.2 and now
the patch causes each addressbook to show up twice.  I have verified
that if you remove the patch, rebuild kdepim and then install the newly
built version of kmail, the address book in kmail works as expected.
This is an ubuntu specific problem and is not caused by upstream.
