If you post ASN.1 dumps and expect me to read them, pretty please use
dumpasn1 and not the openssl tools.

4KB is a reasonable size, no specific reason for it.  An ASN.1 parser is
expected to parse it.  It is quite possible that there is a but our
parser but that would be the first report for a couple of years.  

What version of gpgsm are you using? 

  $ gpgsm --version
  gpgsm (GnuPG) 2.0.12-svn4945
  libgcrypt 1.4.2-svn1299
  libksba 1.0.4-svn284

What software created the data?
