Sounds like you're running into cedet-common bug #270388: cedet-autogen.el insists on sticking a nil in load-path, breaking debian-pkg-load-path-item. Arguably, the real bug is that d-p-l-p-i breaks, since Emacs itself permits nil (as a stand-in for the default directory). However, given that few things actually need that feature, and that cedet itself does not actually seem to be among them (as determined empirically by commenting out the offending line), it's probably reasonable to leave emacsen-common as is and get cedet to accommodate it (not a terribly difficult task, so I have no idea why the maintainers have been sitting on it for months). Incidentally, declaring a pre-dependency on emacs21 is definitely *not* the proper solution.
