Some m4a files do not load or play

[Jared Robert]

I'm running Mixxx 1.8.0.2 built with the m4a=1 option in Ubuntu 10.10 from bzr. I have quite a number of m4a files in the music library, but I also have quite a few that refuse to load or play. In order to get the offending file to attempt to play, I have to drag and drop it to the wave form. You can also drag and drop it to the library window and get a slightly different error in the console, but the result is pretty much the same -- you get a pop-up window that says, "The file '/home/jared/Music/Michael Bublé - 10 - Sway.m4a' could not be found." Going to try and attach a problematic m4a file, but here are the console errors:

This looks like libmp4 cannot handle the special characters in the filename. We properly hand it Unicode as far as I can tell.

fixed in lp:mixxx/1.9 r2663

Oh the file names still look like garbage on the command line but everything at least seems to work now.
