scplugin and spotlight
A mystery was solved today! The current build of SCPlugin (v.269) causes the search field of the System Preferences application to not work under Mac OS X 10.4 (Tiger). Specifically, the preference pane for SCPlugin, not the actual extension.
SCPlugin add a contextual menu to Finder for
Subversion. It also is able to “badge”
files in the Finder to show their subversion status. It is a nice tool,
but hardly required. In any case, if you want your searches to work
again, just remove the preference pane for it from
/Library/PreferencePanes. SCPlugin will still work, but you won’t be
able to change the location of the subversion binary or disable the
plugin easily without restoring the preference pane.
