Comment 29 for bug 258936

m4cph1sto:
I feel your pain, I have an external drive and an MP3 player and on both have seen a total of three lines - one for pictures, one for music and one for software; who knows just how many could be displayed with the right (wrong) combination of folders. I also vote for this feature to be permanently disabled via an option within Nautilus.

Cuchaz:
Your solution is ok but would need some level of persistence or would end up just being annoying, having to dismiss the panel each time you browse back to the original location.
