Please tell me that the ASN.1-sequence "0\5\2\1\3B\0" doesn't contain a
valid unbind requeste. As this was sent via a unix domain socket, I
can't use Wireshark on it. However, Wireshark considers the same sequence
sent via TCP a correct unbind request.

| write(4, "0\5\2\1\3B\0", 7)             = 7
| close(4)                                = 0

Can you quote the standard why you consider this an error condition? 5.3
tells me:

So while it is not the normal termination of a connection, it is no
error condition.

Also, if it is an error, the message must contain enough information to
identify the culprit. But it is written as a debug message without any
of this.
