dwarf-manage gives permission denied error when run as non-root

[tpot]

Should there be a better error message here?

debian@dwarf:~$ dwarf-manage db-dump
Traceback (most recent call last):
File "/usr/bin/dwarf-manage", line 102, in
level=logging.DEBUG)

hdlr = FileHandler(filename, mode)

StreamHandler.init(self, self._open())

stream = open(self.baseFilename, self.mode)

Maybe default logging to stdout with a warning saying that the log file couldn't be written to. I guess it depends on the permissions on the database file whether running db-dump as non-root even makes sense.
