Steps to reproduce: 1. Open KMail settings 2. Add new identity 3. Enter a name and press Enter or press the appropriate Alt-shortcut to trigger the OK button. Actual result: The dialog does not close. All other keyboard shortcuts in the dialog work as expected. Expected result: Pressing Enter (this may be open to debate) or pressing Alt+O should apply the settings and close the dialog, just as clicking the OK button does. Additional information: First encountered this with the German locale, but to rule out a translation problem, I was able to reproduce with US English.
