I found it. The culprit was on the following line from nose:

return parser.parseArgsAndConfigFiles(argv[1:], cfg_files)

http://code.google.com/p/python-nose/source/browse/nose/config.py#261

When you pass an argv, the first element in the list is dropped. From
the command line, the first argument is the nosetests script, but when
passing it programmatically, I only passed in the real arguments. In
my case, the "--where" option was dropped, taking the folder location
and the module as 2 paths to run tests from.

Either this is a bug or expected. If it is expected, it should be
documented more thoroughly.

Greetings,

Ringo
