French characters issue

Hello,
First of all, many thanks for this great tool.
Of all the jukebox softwares I've tried, SubSonic is by far the best one - at least for my way of sorting my musical files ^_^
I've got a small issue with French characters : é, à, etc.
I can't see the folders with those characters in their names, and the sorting of the mp3 files is messed out when those characters are in the names.
Folders as seen in SubSonic :
SSH (ls) :
As you can see, 3 folders can't be seen with SubSonic...
Inside a folder with SubSonic :

The only topics I've found with the same issue are those :
http://forum.subsonic.org/forum/viewtopic.php?p=1840
http://forum.subsonic.org/forum/viewtopic.php?p=1921
But they weren't useful...
I'm running SubSonic Version 3.4.beta1 (build 525), Server Apache Tomcat/5.5 (72.4 MB / 108.5 MB) on a Debian 4.0 box.
My mp3 files are stored on the server and I have no problem with their filenames (as seen on the screenshots).
Any ideas ?
EDIT :
I've found this post which talk about the same issue :
http://forum.subsonic.org/forum/viewtopic.php?t=689
I've tried to change the encoding from ISO-8859-1 (the one by default) to UTF-8 and to ISO-8859-15 with no succes...
EDIT 2 :
Ok... Now it's getting weird :
I've tried to make a french translation by editing locales.txt and by adding a file named ResourceBundle_fr.properties.
That broke completely Subsonic (java errors everywhere, even by trying to do it the cleanest way -by stoping/restarting tomcat...)
So I choosed to redeploy the .WAR file, and now it's working...
I'll try later to redo a french translation, if you're interested, I'll post it in the forums.
EDIT 3 :
The problem is still here but not all the time...
It seems that the folders/files with accents in their names disappear after a certain amount of time...
If I restart tomcat5.5, it's working again... until next time.
