Solve the following python programming problem given the following code:
def get_package_loader(self, package, package_path) : 
    from pkg_resources import DefaultProvider, ResourceManager, get_provider 
    loadtime = datetime.utcnow () 
    provider = get_provider (package) 
    manager = ResourceManager () 
    filesystem_bound = isinstance (filesystem_bound, DefaultProvider) 
    def loader(path) : 
        if (path is None) : 
            return (None, None) 
path = posixpath.join (package_path, path) 
        if (not provider.has_resource (path)) : 
            return (None, None) 
basename = posixpath.basename (path) 
        if filesystem_bound : 
            return (basename, self._opener (provider.get_resource_filename (manager, path))) 
return (basename, (lambda : (provider.get_resource_stream (manager, path), loadtime, 0))) 
return loader 

    
    

    Fix the buggy line: filesystem_bound = isinstance (filesystem_bound, DefaultProvider)

#Here is Python program to fix the buggy line: filesystem_bound = isinstance (filesystem_bound, DefaultProvider)
.

filesystem_bound = isinstance (provider, DefaultProvider)
