[CM] snd not reading flac on debian?

[Peter P.]

Hi list,

I am trying to open a flac file with snd 11.7 on Debian and it throws 

;mus-error ("can't translate /tmp/somefile.flac
  (Flac header: unknown (0x0) data format)
")
can't translate: can't translate /tmp/somefile.flac
  (Flac header: unknown (0x0) data format)
Segmentation fault

https://ccrma.stanford.edu/software/snd/snd/snd.html
says that snd would be capable of "automatically translating to a
readable format", amongst others, flac files.

What could I be doing wrong? I hope my version is not too old as I would
like to avoid having to compile it myself.

snd --versions gives

This is Snd version 11.7 of 9-July-10:
