Version: 1.9.1 (using KDE 3.5.0 Level "a" , SUSE 10.0 UNSUPPORTED) Compiler: Target: i586-suse-linux OS: Linux (i686) release 2.6.13-15.7-default trying to add a vcard for existing primary address gives an error message. IMHO it should (also) give the user the choice to *) open the existing addresse *) import it nevertheless (instead of telling the user to save and import manually) eventually show the difference between existing and new address. the german "Adresse aufrufen" (call address) also wants to add the vcard instead of opening it.
Thank you for taking the time to file a bug report. KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2. We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
