    Fixed memory leak when parsing fails for a child element of a Path
    
    A GXPSPath struct is leaked when parsing fails for a child element of
    a Path.  Parsing is aborted when invalid data is encountered and
    cleanup code is not run.  This adds a error handler to the path
    GMarkupParser to free the struct on error.
