RE: evolution 3.14.4 running under Ubuntu 14.04 64-bit

Last evening, I received a "bad" e-mail from a trusted client.  Each time I clicked on the e-mail, evolution closed.  I waited until I received another e-mail and I forwarded the "bad" e-mail and the one immediately before and immediately after to one of my yahoo e-mail accounts and then I deleted the "bad" e-mail.  Before I deleted the "bad" e-mail, I started evolution from the CLI.  Evolution started but gave the following message:

camel-WARNING **: Failed to initialize NSS SQL database in sql:/etc/pki/nssdb: NSS error -8187

Even though I deleted the"bad" e-mail and emptied Trash, it still get the camel-WARNING.  For example:

john john-Vostro-3500:~$ evolution

How do I fix these problems?
