Solve the following python programming problem given the following code:
@ staticmethod 
def FindPathByUuid(path, uuid, arch) : 
    def ViewfinderPath(uuid) : 
        p = os.path.join (_VIEWFINDER_DSYMS_UUID_PATH, uuid) 
        if (not os.path.exists (p)) : 
            return None 
p = open (p).read ().strip () 
        if (not p) : 
            return None 
return os.path.join (_VIEWFINDER_DSYMS_PATH, p, _VIEWFINDER_DSYMS_SUFFIX) 
def DsymForUuid(path, uuid, arch) : 
        dwarfdump = subprocess.Popen (['dwarfdump', ('--arch=%s' % arch), '--uuid', path], stdout = subprocess.PIPE, stderr = subprocess.PIPE) 
        for line in dwarfdump.stdout : 
            if (uuid in line) : 
                return ' '.join (line.strip ().split (' ') [3 :]) 
return None 
try : 
        p = uuid_cache [uuid] 
except KeyError : 
        p = ViewfinderPath (uuid) 
        if (not p) : 
            mdfind = subprocess.Popen (['mdfind', ('com_apple_xcode_dsym_uuids = ' + uuid)], stdout = subprocess.PIPE) 
            try : 
                p = iter (mdfind.stdout).next () [: (- 1)] 
                if p.endswith ('.xcarchive') : 
                    dsym_folder = os.path.join (arch, 'dSYMs') 
                    dsyms = glob.glob (os.path.join (p, 'dSYMs/*.dSYM')) 
                    if (len (dsyms) == 1) : 
                        p = os.path.join (p, 'dSYMs', dsyms [0]) 
else : 
                        p = None 
except StopIteration : 
                p = None 
mdfind.wait () 
if p : 
            p = DsymForUuid (p, uuid, arch) 
else : 
            global symbol_dirs 
            for d in symbol_dirs : 
                p = ('%s/%s' % (d, path)) 
                if os.path.exists (p) : 
                    p = DsymForUuid (p, uuid, arch) 
                    if p : 
                        break 
p = None 
uuid_cache [uuid] = p 
return p 

    
    

    Fix the buggy line: dsym_folder = os.path.join (arch, 'dSYMs')

#Here is Python code to find = subprocess.

dsym_folder = os.path.join (p, 'dSYMs')
