[Evolution] Evolution crashed on receiving new mail

[John Lauterbach <lauterba bellsouth net>]

Evolution crashed when receiving new mail.  It will not restart normally.  Starting form command line gives:

 john john-Vostro-3500:~$ evolution

(evolution:20042): camel-WARNING **: Failed to initialize NSS SQL database in sql:/etc/pki/nssdb: NSS error -8187

(evolution:20042): GLib-GObject-WARNING **: cannot register existing type 'CamelEwsStore'

(evolution:20042): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed

How do I fix this problem.  Evolution is mission critical.
