I've had all sorts of problems with Nose -- it seems to do tons of tricky things that start to fall apart on more complex code bases. It interferes with namespace packages, it changes the current directory when it runs your tests, one time it caused every one of my tests to fail because we added a module-level variable named __metadata__ to one of our files, aaagggghhh.
I finally gave up and wrote my own unittest loader plus some monkey patches. It supports the key features of Nose (for me) and doesn't cause weird problems.

I've reproduced this problem outside of TG2: http://paste.turbogears.org/paste/6992 Looks to me like it's an issue in coverage, nose, or sqlalchemy, especially since it only appears when --with-coverage is used.
