Version: (using Devel) OS: Linux Installed from: Compiled sources In KMail configuration dialog, Accounts section, click Add, and select Local mailbox. At the bottom of the dialog, it will say "&Destination folder". I'm using KDE 4.2 RC.
Also, there's a "File &location" in the same dialog.
Confirmed both typos in svn trunk r909527
SVN commit 914015 by mlaurent: Remove "&" which is not correct (I don't think that I can backport to kde4.2)
Thanks!
