Thank you to everyone involved!
Recently I also updated the GtkSearchEngineTracker implementation to not use hacky dlopen() calls and to use DBus instead. This avoids us updating the work for each new version of Tracker that comes along too. The patch attached to the bug (658272) should be applied soon (given Matthias was pushing for this sooner rather than later). So, we’re all on track!
