Not sure about this: it only affects one of the supported platforms, and not having it supported on Windows didn't block earlier releases either.
(TBH the feature isn't "stable" on Mac OS X with Inkscape 0.48.x either: import from OpenClipart can only be used once in the current session - if called a second time within the same session, it results in a crash as well (bug #365567, comment #4 and below))
