Hmm.  Can you try running with -v?  That will tell us exactly which 
command it is running, and hopefully we can work backwards from there.

Long shot, but is the kernel on that machine recent?

The only thing that changed from v0.47 is the below.  Can you try 
replacing 'btrfs device scan || btrfsctl -a' with 'btrfs device scan ; 
btrfsctl -a'?  Maybe the btrfs tool isn't being pendantic about return 
codes...
