Version: (using KDE 4.3.0) OS: Linux Installed from: Ubuntu Packages When right clicking an application button in the task bar, the allocated menu area is the same as the button width. However, the actual menu size is smaller, rendering an unusable block in the right side of the menu. Easily reproducible when there are few open applications. Perhaps it's the kubuntu packages fault? Actually I'm on 4.3.1, but it was not available in the bug report page, so I selected 4.3.0. And it's there since 4.3.0 anyway.
