Forgetting to add a file can be a nasty one, since if you discover that too late, the original file at patch time might not exist anymore (how do you guys solve this? Just plain discipline I guess?).

I've done this once, but with the cabal dependencies, not darcs. Thus the uploaded sdist was missing one of the source files, and consequently failed to build.

I suppose the best way is to test this with a separate test repository which you don't touch, except from pulling from your development repo and checking that it builds.

For what its worth, the darcs "test" preference performs the tests in a completely fresh working tree that it creates ONLY using files that have been checked in. This helps avoid the problem of things only working "accidentally", because of uncommitted changes.
