The message means exactly what it sais, that you try to reduce the ref count of an object that doesn't exist. If it is a C-program the way to trace this is to rerun the program with the flag g-fatal-warnings in which case the program will exit such that if you run the program in a debugger, the error will be caught and you can examine the stack and the reason for the error.
But since the example you give is in Python this probably means that there is an error in the python binding. You should try to create a minimum example that triggers the problem and try to create a bug report.
