This idnicates that the data is okay.

There is a spurious byte with the value 0x14 (^T) somewhere outside
the signed data - probably even outside the encrypted data.  Check
whether the encrypted message as this byte appended.

This is not possible becuase the signed data is encrypted and to check
the signature it obviously was decrypted.

Run gpg with the option -vv this should yields a lot more debugging output.
