Comment 2 for bug 531939

Other users reported similar bugs on ubuntu-fr forum (http://forum.ubuntu-fr.org/viewtopic.php?pid=3555550 e.g)

I suggest to fix this bug by filling the 3 parameters (Title, Artist, Genre) by default (instead of blank) if the CD does not provide any information.
For example, if a CD does not provide any information about Artist, then, insert "unknown" in Artist by default instead of blank, so that Sound-Juicer does not crash when trying to extract songs in a blank repertory (if the user chose in the Preferences to extract in a "Artist" type folder).

Hope this helps making Sound-Juicer better :)
