The crash when open the pref pane was caused by a bug in some code provided by Apple (the LoginItem API). It would fail to read login items that had non-ASCII characters in the path name. Thus, only users who had certain login items installed would experience the a crash. The new version 1.0.1 fixes this--fortunately the API is provided as code by Apple and could be fixed.
