Crash on

[John Pye]

Hi all

I have a unittest test suite that's testing a fairly large SWIG-wrapped
application via Python. All my tests are passing at the moment, but
when Python exits, I get the following (shown below).

Could anyone please help me to understand what precisely this message
means (other than that obviously I have made a mistake with object
ownership or INCREF or DECREF somewhere), and what the best way of
tracking down the source of the problem might be?

Cheers
JP
