[Evolution] Certificate failures.. apologies if I've asked before

[Anonymous Japhering <japhering gmail com>]

Kernel: 5.4.0-72-generic x86_64 bits: 64 
Desktop: MATE 1.22.2 
Distro: Linux Mint 19.3 Tricia 
Evolution: 3.40.1 (flatpak gitc7adee9) 

With the move up to 3.40.1 ,  I seem to be seeing significantly more  of the
following error: 

   GLib-Net:ERROR:../tls/base/gtlsconnection-
   base.c:1394:g_tls_connection_base_handshake_thread_verify_certificate: assertion
   failed: (priv->handshake_context)
   Bail out! GLib-Net:ERROR:../tls/base/gtlsconnection-
   base.c:1394:g_tls_connection_base_handshake_thread_verify_certificate: assertion
   failed: (priv->handshake_context)
   /app/bin/evolution: line 33:    44 Aborted                 (core dumped)
   /app/bin/evolution.bin "$@"
   
Everything is fully patched. It seems to happen most frequently when I go on a
deletion binge, deleting a series of messages based on what I see in the preview
pane ( I rarely open messages in to a new window ).  Size of series can be
anything from 3 to 30+.

I've had it happen on free gmail accounts, G-suite accounts and Office365
accounts. Current mix is  2, 3, and 1 respectively.

No messages on the console. Nothing to indicate a network blip (I've almost
always have 3-5 vpns open to different systems.

Thoughts?
