I thought it's obvious: It is most likely a problem caused by the broken 
bit #defines in the Linux kernel for the SCSI status byte. I assume that
status should be 0x02 instead of 0x01. In addition, I would guess that
for the same reason, a kernel instance did not fetch the sense data as
libscg should try to work around these Linux bugs if at least the first 
sense byte is != 0.
