That error would most likely occur of the identityfile is the wrong 
format
or is corrupt somehow (the first 4 bytes are the length). Is it using
the converted (OpenSSH format) private key (the output from 
dropbearconvert)?
The output from dropbearkey should be usable as-is on dbclient, without 
conversion.

If you don't have any success, generate a new test key and send it, I'll 
have a look.

Cheers,
Matt
