Version: (using KDE KDE 3.5.7) Installed from: SuSE RPMs There are probably easier ways to trigger this, but 1) While in Folder A, drag folder B to folder C. As B is dragged over the follder list, the window title bar changes to the folder currently under the mouse. 2) Drop B on C 3) On the drop popup menu, select cancel. The headerview stays in A but the window title bar stays C.
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.
