The order that things get destroyed isn't always clearly defined. Is it possible to do the cleanup work before interpreter shutdown? Alternatively: maybe take a local reference to the exception types you need to refer to (just "AttributeError = AttributeError" at top level should do it), which should keep them alive longer (I think). Worst case, capture *all* exceptions, then look at e.__class__.__name__ and match on that. ChrisA
OK - not solved but resolved anyway. The Django project was failing on the new server and working fine in dev.The problem seems to be a mis-export from an old subversion repo.The project was being reconstituted on a new staging server from a reloaded svn dump from the old (ancient) svn server to the new svn server on the same machine.
Resolution "happened" when I updated the (c) notice in all source files and recommitted to the new server and re-exported from that. The repo looks fine. The log is all there back to the beginning. As a test I have deployed from an earlier revision and that all works. It's either a miracle or I did something else (which I didn't notice) which fixed it.
