I don't know how to cut a piece of the first file without re-encoding it, so as
to attach it here.

I will try to attach the second file.

Note:
When I imported the first file in Audacity,
... and then exported it as flac, 
... and then used k3b to create an Audio CD with the new flac file
... and then chose to export the sound of that CD
the created wav file had sound.

This "successful" flac file that was created by Audacity was like this,
according to mediainfo...

So, the issue might have to do with the fact that the initial flac files were
encoded with "libFLAC 1.2.1 (UTC 2007-09-17)".


STEPS TO REPRODUCE
1. See bug 418079 --> STEPS TO REPRODUCE --> Version 1


OBSERVED RESULT
Again, see bug 418079 --> OBSERVED RESULT --> In version 1


EXPECTED RESULT
Sound in the files, or a warning of no sound in the files.
