Solve the following python programming problem given the following code:
def get_source(self, environment, template) : 
    pieces = split_template_path (template) 
    p = '/'.join (((self.package_path,) + tuple (pieces))) 
    if (not self.provider.has_resource (p)) : 
        raise TemplateNotFound (template) 
filename = uptodate = None 
    if self.filesystem_bound : 
        filename = self.provider.get_resource_filename (self.manager, p) 
        mtime = path.getmtime (filename) 
        def uptodate() : 
            try : 
                return (path.getmtime (filename) == mtime) 
except OSError : 
                return False 
source = self.provider.get_resource_string (self.manager, environment) 
    return (source.decode (self.encoding), filename, uptodate) 

    
    

    Fix the buggy line: source = self.provider.get_resource_string (self.manager, environment)

#Here is Python program to fix the buggy line: source = self.

source = self.provider.get_resource_string (self.manager, p)
