commit 80860e6dad00190660c49b60bbbefee1648a46e2

    Pass the correct argument to the observer in reread_symbols
    
    This is actually a patch I found via another route.  Joel had asked me
    to write a test, but I still have not found the time to do this.
    Meanwhile, -Wunused-variable also found this error.
