In Browse Music Folder:

I have a directory that contains a symbolic link to another directory on another disk
ie.:

Rock
   |
    - Led Zep (Symoblic link)
    - Slade 
    - Saxon

Three rows appear except the 1st has a blank name. If you select one of the icons on the right the files 
in the Led Zep directory are added to the play list. However as there is no Led Zep link it is not possible to drill down any further
buy turning on d_files

it can be seen that normal directories do not return a following / however symbolic links do:

extracted /Music/Rock/Led Zep/ from file url file://Music/Rock/Led Zep/
.....
extracted /Music/Rock/Slade from file url file://Music/Rock/Slade
....
extracted /Music/Rock/Saxon from file url file://Music/Rock/Saxon

this seems to be significant as I added 
   $file=~s!/$!!;

to pathFromFileURL in Slim/Utils/Misc.pm

and it fixes the problem but this may not be the best fix! (maybe better to fix the url rather than the file as per all of the other fixes)
This never happened in earlier versions.
