By default, this appears to be an akonadi resource, which caused kaddressbook to crash (likely because I had not configured it). Since I don't use akonadi and likely won't until a year or two from now, and since I don't have any addresses in this unused akonadi resource, there is no point in having an akonadi address resource, so I deleted it. Then, since all my addresses are in a traditional vcf file, I asked kaddressbook to open a different addressbook, namely the real vcf addressbook. Once done, kaddressbook now started up without crashing. Since kmail and kontakt make use of the addressbook in kaddressbook, this could (?) be a problem.
