Thanks for your help.
Yes, it was .wma files. I have make test with .mp3 and all works fine with them.
So, it's a conflict with this kind of files. Reencode is a good thing, but ... 80 to 90% of my audio files are in .wma and it makes a very huge number of files to reencode !
So, if there is a solution to fix the problem with .wma, it would be fine too.
I also run clementine from the terminal and here is the full output :
