It does indeed look strange.

That's what I'd do.

Or you can experiment with the utilities that I ship with my software 
TPM, which bypass Trousers completely and go directly to /dev/tpm0.

Or you could use trousers, but run them through the proxy that I ship 
with my SW TPM and examine the actual byte streams.

Or you could run trousers in verbose mode and examine the byte streams.

No.  Sorry.

At the TPM level, there is no actual getpubek or ownerreadpubek command, 
so I can't even tell exactly what was running.  It seems unlikely that 
there would be a bug in the TPM tools at this point.

The ReadPubek command (probably what's running) is often disabled, so I 
thought you might be missing an error code and dumping garbage. 
However, if the public key is correct, that's unlikely.
