Could'nt format CD-RW containing audio tracks

Binary package hint: brasero

[This is my first bug report so I'm apologies about missing elements for your comprehension . Please ask me if you want more informations :-)]

Ubuntu 7.04
Brasero 0.5.2

After insertion of a CD-RW containing audio tracks application Sound Juicer (2.16.3) starts automatically. I close Sound Juicer and launch Brasero in order to format the CD. The format is impossible : pop-up message "Formatage impossible. Extraction audio en cours" (original message in French language which could be translated as "Unable to format. Audio extraction in progress").

I close Brasero and launch GnomeBaker to format my CD (no problem with this application). CD media is ejected and inserted again. I launch again brasero (after closing GnomeBaker) and make another audio compilation. I try after to burn my compilation but i get the message "Gravure impossible. Extraction audio en cours" (original message in French language which could be translated as "Unable to burn. Audio extraction in progress).

After rebooting Ubuntu (hardware reboot). I can normally use Brasero to burn my compilation.

No problem with Format and burn after if the CD-RW contains Data.

Thank you for your attention.

Regards.

Manu.
