If you remove (via rm, or whatever) a plugin while it's enabled, the enabled setting of that plugin remains in LocalSite.cfg, leading to a somewhat confused InstalledPlugins page. (Well, really, the relevant variables therein.)

This is a design constraint of manually enabling/disably plugins (not true plug & play.)

A sensible fix is to silently drop a Plugin if the Plugin topic and .pm file cannot be found.

Silently dropped plugins are a nightmare for an installer to debug. There needs to be as much feedback as possible re: the plugin. If it is enabled in the cfg, then it is expected to be present. ACTIVATEDPLUGINS and FAILEDPLUGINS should be used as advised for working out why a plugin fails.

I just tried deleting the SlideShowPlugin, by deleting the .pm and then the plugin topic. In both cases the diagnostics on the InstalledPlugins page are excellent.

Discarding.

May be we should rename the Plugin API to "plug-configure-unplug-configure API"
