Segmentation fault on NULL pointer dereference

I'm using version 0.2.0 of libkmip based off commit 5b4e67, with my custom application in which I connect to pyKMIP server using libkmip library. When pyKMIP server time is not synchronized with my server, that is my server time is in future relative to pyKMIP server time, pyKMIP server rejects requests from my server with following error: 2019-12-16 10:05:37,450 - kmip.server.engine - WARNING - Received request with future timestamp. Received timestamp: 1576515938, Current timestamp: 1576515937 I believe that it is fine for pyKMIP server to reject such request, but when my server receives response with indication of that error then app crashes. I have invesitgated that problem a little bit and found out that there is a likely problem in the libkmip library code:

#0  0x0000000000424e5b in kmip_bio_create_symmetric_key (bio=0x6649e0, template_attribute=0x7fffffffcf50, id=0x7fffffffd010,

197     result = resp_item.result_status;

(gdb) p resp_item.response_payload 
$6 = (void *) 0x0
(gdb) p resp_item
$7 = {operation = (unknown: 0), unique_batch_item_id = 0x0, result_status = KMIP_STATUS_OPERATION_FAILED, 
  result_reason = KMIP_REASON_INVALID_MESSAGE, result_message = 0x6648d0, asynchronous_correlation_value = 0x0, 
  response_payload = 0x0}
(gdb) c
Continuing.

Program terminated with signal SIGSEGV, Segmentation fault.
The program no longer exists.

Actual crash happens in line 200 of kmip_bio.c. while unique_identifier is being dereferenced. I think it should be conditionally dereferenced when resposne result_Status is success. In my scenario respons result is INVALID_MESSAGE (I believe that due to time synchronization problem that I described earlier)

(gdb) p resp_item
$7 = {operation = (unknown: 0), unique_batch_item_id = 0x0, result_status = KMIP_STATUS_OPERATION_FAILED, 
  result_reason = KMIP_REASON_INVALID_MESSAGE, result_message = 0x6648d0, asynchronous_correlation_value = 0x0, 
  response_payload = 0x0}
