I've got no idea what this means... Anyone want to give me a clue?

Traceback (innermost last): File "/home/mailman/cron/qrunner", line 276, in ? lock.lock(timeout=0.5) File "/home/mailman/Mailman/LockFile.py", line 219, in lock self.__write() File "/home/mailman/Mailman/LockFile.py", line 350, in __write fp = open(self.__tmpfname, 'w') IOError: [Errno 13] Permission denied: '/home/mailman/locks/ qrunner.lock.epuk.thenexus.co.uk.4399'

I've got lots the same! Oh!, and the list I'm trying to set up doesn't work too well. I thought I was doing well setting up a test, the real thing's harder!
