Version: (using KDE 4.0.3) Installed from: Ubuntu Packages Once you add a superkaramba plasmoid to the tasktray there is no normal method for removing it. Right clicking will only allow you to update the plasmoid.
I guess you mean you can't remove the superkaramba plasmoid from the panel containing the taskbar.
Indeed, sorry for the incorrect use of terms.
This is an issue with superkaramba. In particular, the Karamba::preparePopupMenu() method creates its own popup menu that doesn't include a close action if it's attached to a QGraphicsView (as it apparently is on the panel and desktop). Really, Superkaramba themes in plasma should export their popup menus using Applet::createMenu(), and thereby allow the containment they are in (such as the panel or the desktop) to add standard entries like "Remove this [applet name]" and a Panel Options submenu. That is probably an unreasonable change for the 4.1 branch, though, and may not work with the structure of SuperKaramba anyway.
Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I am closing this bug.
