Affects: rhythmbox (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
My paths use mixed cases; using rhythmbox to add an automatic playlist,
entering the correct part of the path, doesn't work as expected.  The
detection only finds lower-case paths, and spaces, brackets, etc, have
to be changed to %xx manually.

As an example, my directories look something like this:
music/
    Soft pop/
        song1.mp3
    Pop & Rock/
        song2.mp3
        song3.mp3

If I enter 'pop' or 'Pop' as the path in the automatic playlist path
portion, it only gets the stuff in "Soft pop".  If I enter 'Soft pop',
'Soft%20pop' or 'oft pop' it finds nothing.  Entering 'oft%20pop' will
also find all files under "Soft pop".

If I enter "Rock", "rock", "Pop & Rock", or "Pop%20%26%20Rock" it finds
nothing.  If I enter "ock", it finds all the files under "Pop & Rock".
