Small Fedora problems and fixes
From WBITT's Cooker!
Problem: Fedora 13. Tried to install "Task Timer" widget for KDE plasma. but when I placed it on the desktop, it showed "Could not create a python script engine" in the widget window.
Solution: "yum install kdebase-workspace-python-applet"
Additionally, try installing the following for extra built in widgets: "yum install kde-plasma* kdeplasma-addons"
