Nose 0.10.0 breaks on multiple tests

[GoogleCodeExporter]

1. Test runs OK by itself 

$ nosetests --verbose -a tags=buildbot --with-isolation --stop
--exclude=TestClientCheckableDirModel.py UnitTests/TestAccount.py
test creating an empty account object ... ok
We have to do a boootstrap to have something to load ... 2007-11-07

2007-11-07 07:48:44,317 update_schema        DEBUG Nos schema updates
directory, ignoring
ok

OK

2. When two tests are run the test aborts in setup_module() (these worked
in 0.9.0)

$ nosetests --verbose -a tags=buildbot --with-isolation --stop
--exclude=TestClientCheckableDirModel.py UnitTests/TestAccount.py
UnitTests/TestLRUCache.py
ERROR

What I think is happening is that nose 0.10.0 is calling setup_module()
when it loads the test, whereas nose 0.9.0 was calling it before it ran the
test. This breaks all our tests.

If you could attach a simplified example that shows this error, that would be 
very
helpful in tracking it down. I suspect that the problem is actually in the 
isolation
plugin, also, so can you explain why you're using it and if you get any 
different
results without it?
