First run of 'gnumeric' segfaults on exit?

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

After updating 'gnumeric' via pkgsrc-2017Q4 (NetBSD/amd64-8.0_BETA), I
have observed that its first invocation after logging in segfaults on
exit:

Core was generated by `gnumeric-1.12.36'.
Program terminated with signal SIGSEGV, Segmentation fault.

Subsequent invocations during the same session do not segfault.

Anyone else seeing something like this?
