I've created a significant hierarchy of playlists based on the source (for
example, a dir-tree of Magnatune playlists sorted by genre).  Previous to my
latest upgrades, when I would "Browse the Playlists," it would allow me to
follow the directory tree, which is what I wanted.

Now, it seems, every m3u file in the entire playlist directory chain is being
listed together.  So, by illutration, Browse Playlists used to "look" like this:

          Browse --->
                 magna     ----> ambient ----> Rapoon.m3u*
                 npr             blues
                 radio1234       metal
                                 whatever

Now, I just get ALL of the m3us in each of the subdirs above, sorted by alpha. 
One long, hard to nav list.

I am delighted to provide samples, logs, etc.
