Tried that and piped it to a log file.  No difference in behavior and
nothing significant in the log.  Here it is in case I'm missing
something:

# tail -f evolution.log
CalDAV Eplugin starting up ...
** (evolution:8730): DEBUG: mailto URL command: evolution --component=mail %s
** (evolution:8730): DEBUG: mailto URL program: evolution
libnm_glib_nm_state_cb: dbus returned an error.
  (org.freedesktop.DBus.Error.ServiceUnknown) The name
org.freedesktop.NetworkManager was not provided by any .service files


That's it.  Evo waits forever saying it is sending message 1 of 1 and
never sends and never gets past the 'Send & Receive Mail' windowlet
that pops up.  I have to cancel.

After canceling this pops into the log:

(evolution:8730): camel-local-provider-WARNING **: Didn't get the next
message where I expected (677) got 0 instead

Let me know what you think.
