weird behaviour when adding nested dirs

[daviddias]

I noticed a weird behaviour when adding nested dirs with go-ipfs, it seems that ipfs add -r freaks out if a dir is empty and exits prematurely

» ipfs version
ipfs version 0.4.0-dev

» ipfs add -r dir-big

@diasdavid can you write a small test script to reproduce? i.e. mkdir -p a/b/c && ipfs add -r a

While I was preparing the script for you, I saw it failing again several times, but now, after I tar'ed it and added to IPFS, and finished the script that would download from ipfs, untar and ipfs add -r, it started working!! Then I went back to the original dir-nested where I was seeing the error and it doesn't happen anymore and I seem unable to make it fail again 😧
