For those more familiar with bsddb, it's the test_1413192.py module in lib/bsddb/test that tickles the problem. It should have been more obvious, since I saw the 1413192 in the module name during exit cleanup, but mentally ignored it as an internal identifier of some sort. The test module clearly leaves an open transaction, but also purges its working directory, so maybe that's why the log file is missing. But since the test was specifically against object destruction, I'm not sure how best to restructure (maybe make env_name into a class that only prunes the directory in __del__? Although that would affect GC and thus destruction order too). This test has been around a bit, but the pruning of the directory was backported recently, which is probably the source of the problems. -- David
