but a small new bug is introduced: closing tabs in "konsole" is working only via menu because the symbol in the tablist is inactive and my configured middle-click on the tab is also ignored
According to what I have read this is on purpose. In order to fix a crash some close methods from the konsole have been deactivated.
See the konsole part on http://www.kde.org/announcements/changelogs/changelog4_6_0to4_6_1.php
