Since updating plasma desktop to 4:5.6.5-1, the context menu on unlocked widgets no longer appears when the mouse is right clicked. First noticed on the application menu as the menu can no longer be accessed to edit the content or to create or re-sequence the menu items but other widget context menus (e.g. on the waste basket) are no longer available. Behaviour does not change irrespective of whether widgets are locked or not. Reproducible: Always Steps to Reproduce: 1. Right click on any widget. 2. 3. Actual Results: No context menu with widgets locked or unlocked. Expected Results: Context menu to edit settings.
Reassigning. Can't reproduce, though. Maybe run plasmashell from a terminal and watch for interesting output.
Seems there's some issue in Debian packaging or its upgrade process? *** This bug has been marked as a duplicate of bug 365180 ***
