asyncio await on_connect crash with ev->state != PYCBC_EVSTATE_ACTIVE when using SSL

A crash results with the following error when using Python asyncio and SSL ("couchbases" scheme) to connect to Couchbase. The error does not occur and everything works normally when using a non-SSL connection (using either the "http" or "couchbase" scheme).

Error:

python-couchbase: ev->state != PYCBC_EVSTATE_ACTIVE at src/iops.c:505. Abort

The attached program can be used to reproduce the error.
