Can't see files in folders with special characters

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a folder in your music directory and give it a name with a special 
character (in my case it's Sweex\x20MP4, where \x20 represents a space). Also, 
create a few additional subfolders without special characters.
2. Put some music files in that folder and its subfolders.
3. Browse the folders you created with MPM.

What is the expected output? What do you see instead?
There should be files in the folders you just created. However, I can't find 
them anywhere in MPM. I can see all the folders that are there, but the files 
don't show (center pane does not change). In the bottom bar I get an "ACK 
[50@0] {add} directory or file not found" error. It's not a permission issue 
since I tried setting permissions to 777 to no avail.

What version are you using? On what operating system?
Music Player Minion: 2.1.1
Firefox: 3.6.13
Music player Daemon (MPD): 0.15.13
OS: Client: Windows 7 Ultimate (6.1.7600)
    Server: Gentoo GNU/Linux 2.6.34-r12

Please provide any additional information below.

To me it seems like a problem with escaping special characters. I could rename 
the folder (actually, it's a mount point) but there's a problem with that. I 
set up my server to auto mount all removable media to my mpd music folder so I 
don't control the names of the mount points and the folders on the removable 
media.

Just a small addition: the error "ACK [50@0] {add} directory or file not found" 
is different depending on the action I try to perform. The {add} part is used 
when I try to add an affected folder to the playlist. When I try to view a 
folder's contents it says {lsinfo} instead.

One last thing: the problem seems to be the backslash only. Other special 
characters (%, $, space, etc) don't seem to cause this problem.
