2011-02-26 Saturday - Aptana Pydev "no such file to load"

I've discovered an issue with the latest release of the Aptana Pydev plugin for Eclipse (Aptana Pydev 1.6.5.2011022501).

An internal error occurred during: "Loading bundle: C:\eclipse\configuration\org.eclipse.osgi\bundles\1026\1.cp\bundles\bundle-development.ruble".
(LoadError) no such file to load -- ruble/ui

Also tote: I'm running Eclipse Helios 3.6.2.r362_v201102120-9gF78Gs1FrIGnHDHWkEcopoN8AmxeZflGDGKQi
Build id: M20110210-1200
