Version: 1.11.0 (using KDE 4.2.0) OS: Linux Installed from: SuSE RPMs In KDE 4.2 KMail the window with the list of messages (top right) is set to display "Current Activity, Threaded". Sorting is on date/time and most recent on the top. Then one would expect to see Today (in Dutch Vandaag) on top. The next label of a thread should be Yesterday. In the attachment two fragments are shown on the left side of this subwindow and the right side. In this picture you see on the top Zaterdag (Saturday in English) which is correct, however one should expect Today (Vandaag). On the next label one should expect Yesterday (Gisteren in Dutch), but it shows Today (Vandaag in Dutch). The rest of the labels, not shown in the picture, are as one should expect.
