I opened a thread in yakkety pre-release testing and can't write to that thread since yakkety is released. To make it short, kaddressbool was crashing since I installed 16.04.
On some forums (I don't remember on which ones) I read, that this is related to contacts with a birthday field.
So I tried this:
1) backup all contacts from ~/.local/share/contacts
remove all contacts from contacts directory (~/.local/share/contacts)
stop akonadi
remove all akonadi related files
start akonadi
Result: kaddressbook starts, is usable, is empty, of course
2) add some contacts to the contacts dir.
ensure that there is no BDAY field in any of them
stop akonadi
remove all akonadi related files
start akonadi
Result: kaddressbook starts, is usable !
3) add all the other contacts to contacts dir. Now there are many of them with a BDAY field.
stop akonadi
remove all akonadi related files
start akonadi
Result: kaddressbook starts, is usable !?!?!?!?
I don't know why, but now it is working.
