This means that there was an error when a DBFFile was instantiated.
SWIG's wrapper objects have an instance variable 'thisown' which is set
a little too late in __init__ so that it can happen that it's not set in
__del__.  In your case this probably comes from a missing DBF file since
that's what you're trying to deal with.  The message is pretty harmless
in most cases.

If we want to fix this properly we either need to use newer versions of
SWIG or not use SWIG at all.
