Rescanning collection gives Invalid filename error

I downloaded and installed the latest version of exaile in bzr (revision 2486). When I try to rescan my collection, I get the following errors:

INFO : Scanning library: file:///home/daw/more/music/taverner

In addition, the collection re-scan never completes: the "Scanning collection" progress bar just stays at 0% and never goes away.

Here's the file that this is probably referring to:

njb3/The Art of Fugue Vol_ 2/(7)Partita sopra Sei gegr��e.mp3

where the two funny characters (after "gegr") are 0xFC and 0xDF, respectively.

This is on a Fedora 11 x86-64 Linux platform.
