kaddressbook-15.12.3-1.fc24.x86_64 akonadi-1.13.0-102.fc24.x86_64 I had a contacts vcard file.vcf with all of my contacts. Whenever I made changes to the information in kaddressbook, the akonadi database was correctly updated, but the updates were not written to my master file resource! I then converted the contacts.vcf file to individual vcard4 files, one for each contact, and made a contacts directory. Again, kaddressbook read all of my contacts into the akonadi database, but, when making updates to the contact information, the revised data was not correspondingly updated in my master vcard file collection. As a result of this bug, I have irretrievably lost much information. Why do the updates not get written to the master resources? Reproducible: Always Actual Results: Edit a contact. Akonadi is updated, but the master file is not. When transferring the master file to a clean install of fedora or to another distro, there is data loss. Expected Results: My updates to my saved contact information must be preserved!
