Segfault?

[Craig Van Tassle]

I'm running gnucash 1.6.14 using a mysql backend on Ubutnu 16.04 I
started having issues today when I was reconciling my accounts. It
segfaults when I try to open it readonly or for editing. 

This is what I get on the CLI.
>gnucash --debug
Found Finance::Quote version 1.38
sys:1: Warning: g_date_time_format: assertion 'datetime != NULL' failed
sys:1: Warning: g_date_time_unref: assertion 'datetime != NULL' failed
sys:1: Warning: g_date_set_dmy: assertion 'g_date_valid_dmy (day, m, y)' failed
**
qof:ERROR:gnc-date.c:1656:timespec_to_gdate: assertion failed: (g_date_valid (&result))
zsh: abort      gnucash --debug


I'm not sure where to go from here. Or if there is a way I can fix it.
