When browsing with "My Music/Music Folder" to a music folder which is like:

~/Music/
    +- album.flc/
        +- 01.flc
        +- 02.flc
        +- 03.flc

Where "album.flc" is a simple directory, and 01.flc, 02.flc and 03.flc are valid FLAC files.
If you browse the dir ~/Music through "My Music/Music Folder" feature, the "album.flc" is detected as a FLAC file, so it is added in the track list linked to the album "No Album" in the database. And you cannot go into it from the web interface since it is considered as a song.

This problem does not show up, whit scanner, but only from the "Music Folder".

Since it was my first bug tracking in SlimServer, I need to touch some files before finding it the Slim::Music::Info::typeFromPath method. I know the workaround (renaming the dir) is much more easy, but not as fun :-)
I think it is the most useless fix :-)
This bug is also present in the 6.5 branch.

Please find my fix below for trunk, it is nearly the same for the 6.5 branch:
