[Evolution] winmail.dat attachment causes 3.16.0 to crash when message opened

[John Lauterbach <lauterba bellsouth net>]

evolution 3.16.0 running under Ubuntu 15.04

Received a message with attachment.  Only way to read it was to group it with message immediately before and message immediately after and forward as attached to a yahoo account on a PC running Win 7 and then use a program called Free File Viewer (I can't get tnef to work).  If I try to open message directly, evolution crashes.  If I run evolution from CLI and then go to the message with the winmail.dat file, I get:

johnl john-Vostro-3500:~$ evolution

(evolution:20446): camel-WARNING **: Failed to initialize NSS SQL database in sql:/etc/pki/nssdb: NSS error -8126

(evolution:20446): GLib-GObject-CRITICAL **: g_closure_unref: assertion 'closure->ref_count > 0' failed

Segmentation fault (core dumped)

johnl john-Vostro-3500:~$  

What are next steps to resolve problem?
