Bug 390965

Application: kaddressbook (5.7.2)
 (Compiled from sources)
Qt Version: 5.10.1
Frameworks Version: 5.43.0
Operating System: Linux 4.15.4-gentoo x86_64
Distribution: "Gentoo Base System release 2.4.1"

-- Information about the crash:
Following a user report I removed kdepim-addons and, after creating a new 'Personal Contacts' addressbook, continued with adding a contact to it. In 2/2 attempts it failed to add the contact.

Immediately after re-adding kdepim-addons I was able to add two contacts flawlessly.

The crash can be reproduced every time.

-- Backtrace:
Application: KAddressBook (kaddressbook), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
