Mac OSX Python 2.4.4 Nose-0.10.0b1 Coverage-2.77
nosetests works just fine
nosetests --with-coverage breaks like this:

I'm seeing the same thing with coverage 2.77 (installed via easy_install) and nose 0.10.0a1
The main script appears to run a second script in coverage-2.77-py2.5.egg/EGG-INFO/scripts which then starts coverage. Except that the second script ends up importing itself despite an attempt to avoid that with.
del sys.path[0]
Installing with easy_install and running with nose produces the error, also then running coverage stand-alone does the same. Downloading the source and installing without setuptools still produces the error on nose, but not stand-alone. That makes sense because nose imports coverage before the coverage script gets its chance to play with sys.path (is this a good thing to do, anyway?).
So there's a quick (hacky) fix. Just delete the coverage script from /usr/bin (or equivalent) and nose will import the correct one first time :)
This could be better solved in coverage by using a setuptools style script. The setuptools docs on script creation describe this.
