Nude Spoons - 2013-12-31

I am using Notepad++ version 6.5.3 (Unicode) and have the Python Indent plugin (version 1.0) installed, and it appears in the drop-down list available from the Plugins menu in the toolbar.

However, Plugin Manager (version does not include Python Indent in its 'Installed' tab; instead it includes it in its 'Updates' tab, noting that the installed version is 'unknown' and that version 1.0 is available.

Even if I opt to install the reported update and allow Notepad++ to restart, Plugin Manager still insists the plugin is not installed and continues to offer the update.

Any ideas as to what is going on here?
