After upgrading from Kubuntu 12.04 (with Kontact 4.8.4 or 4.8.5) to 12.10 (with 4.9.2), auto-completion still does not work, despite information that the problem should have been solved in Kontact 4.9. Restarting computer does not help. Auto-completion DOES work for Recent Adresses however. Contents of Personal Contacts IS available via "Select..."-button on right-hand side of address bar. Reproducible: Always Actual Results: Problem is permanent. Expected Results: Show suggestions for auto-completion from Personal Contacts.
Kmail 4.14.1 I am still having this problem and have for a long time. I would love to know how to fix it as I don't think everyone has it.
This bug has never been confirmed for a Kontact version that is based on KDE Frameworks (5.x). Those versions differ significantly from the old 4.x series. Therefore, I plan to close it in around two or three months. In the meantime, it is set to WAITINGFORINFO to give reporters the oportunity to check if it is still valid. As soon as someone confirms it for a recent version (at least 5.1, ideally even more recent), I'll gladly reopen it. Please understand that we lack the manpower to triage bugs reported for versions almost two years beyond their end of life.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.1 aka 15.12; preferably much more recent), please open a new one unless it already exists. Thank you for all your input.
