Weird mount issue (Ubuntu 18.04, Ceph 14.2.5 & 14.2.6)

Seeing a weird mount issue.  Some info:

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.3 LTS
Release: 18.04
Codename: bionic

Ubuntu 18.04.3 with kerne 4.15.0-74-generic
Ceph 14.2.5 & 14.2.6

With ceph-common, ceph-base, etc installed:

ceph/stable,now 14.2.6-1bionic amd64 [installed]
ceph-base/stable,now 14.2.6-1bionic amd64 [installed]
ceph-common/stable,now 14.2.6-1bionic amd64 [installed,automatic]
ceph-mds/stable,now 14.2.6-1bionic amd64 [installed]
ceph-mgr/stable,now 14.2.6-1bionic amd64 [installed,automatic]
ceph-mgr-dashboard/stable,stable,now 14.2.6-1bionic all [installed]
ceph-mon/stable,now 14.2.6-1bionic amd64 [installed]
ceph-osd/stable,now 14.2.6-1bionic amd64 [installed]
libcephfs2/stable,now 14.2.6-1bionic amd64 [installed,automatic]
python-ceph-argparse/stable,stable,now 14.2.6-1bionic all [installed,automatic]
python-cephfs/stable,now 14.2.6-1bionic amd64 [installed,automatic]

I create a user via get-or-create cmd, and I have a users/secret now.
When I try to mount on these Ubuntu nodes,

The mount cmd I run for testing is:
sudo mount -t ceph -o
name=user-20c5338c-34db-11ea-b27a-de7033e905f6,secret=AQC6dhpeyczkDxAAhRcr7oERUY4BcD2NCUkuNg==
10.10.10.10:6789:/work/20c5332d-34db-11ea-b27a-de7033e905f6 /tmp/test

I get the error:
couldn't finalize options: -34

>From some tracking down, it's part of the get_secret_option() in
common/secrets.c and the Linux System Error:

#define ERANGE          34      /* Math result not representable */

Now the weird part...when I remove all the above libs above, the mount
command works. I know that there are ceph.ko modules in the Ubuntu
filesystems DIR, and that Ubuntu comes with some understanding of how
to mount a cephfs system.  So, that explains how it can mount
cephfs...but, what I don't understand is why I'm getting that -34
error with the 14.2.5 and 14.2.6 libs installed. I didn't have this
issue with 14.2.3 or 14.2.4.

Cheers,
Aaron
