Using Kubuntu(Precise) I am unable to delete a separator(at least if nothing exists below the separator). It will remove itself though after saving and reopening KMenuEdit.
Reproducible: Didn't try
Steps to Reproduce:
3.Expand the Graphics category.
4. Move KColorChooser above the separator.
5. Delete "More applications."
6. Right click on the separator.
The separator can not be manually deleted.
When right clicking a separator I should be able to use the delete entry but it is grayed out.
Workaround: Simply click Save and exit KMenuEdit. The separator will disappear on it's own.
Should share the same cause as bug 296682. Also see https://git.reviewboard.kde.org/r/105778/
