Missing (but irrelivant) source-code causes a failure to generate HTML coverage reprort, non-zero exit code

I'm trying to do a coverage analysis on a large project, some of the components 
(whose content I'm not particularly interested in) are installed as zipped eggs 
and not all eggs include source code.  

In this case, the coverage analysis fails. Nose exits with a non-zero exit code 
No HTML output was produced. The Xunit output file was zero bytes long.

IMO, this feature is not failing safely. On a very big project it's quite 
possible that not all of the source code will be available, especially if the 
developers make use of eggs. It would be better if the coverage report could 
degrade gracefully and not throw a fatal error in the case where it may 
actually pe possible to produce a report, however basic.
