Just for testing purposes, I created a virtual machine with Debian 8.1 running, and the first program I started was Kmail. When the startup-wizard came ("Do you want to create a new mail-account"-Wizard, "Postfach-Assistent" in german), I entered my email and password, it looked it up in the database and got the correct reply-data. When when clicking "next", it only searches again. Then, it shows the correct data again, whilst "next" will still just search again and so on. "Finish" ("Fertig stellen") is greyed out and can't be clicked. This cycle never seems to end, so that the creation of an account becomes impossible and the program renders useless. Reproducible: Always Steps to Reproduce: 1. Start fresh Kmail (probably due to VirtualBox) 2. Enter all the data needed (Email, Password) in the start-wizard 3. Try to finish it Actual Results: The wizard went into a cycle of regaining all data from the database instead of finishing after it once had them. Expected Results: After the correct data was obtained from the DB, it should have been possible to finish the wizard.
It turned out to be just a big usability issue. The "create mailbox"-setting shouldn't be where it is now. It should be where the "finish"-icon in the menu is. Normal users will most probably suffer from this problem.
