PAC core dump after new install

The OS is Ubuntu 17.04.
Perl is 5.24
Hardware is Alienware R15 R4.

I haven't gotten around to installing much on this box yet so it's a pretty fresh install of Ubuntu and PAC. Here is the error I'm getting:

mclark@mikec-alien:~$ pac
PAC started (pac) with PID 6211
ERROR: PAC was unable to load any config file from '/home/mclark/.config/pac'... Now starting from scratch...Use of uninitialized value in string eq at /opt/pac/lib/PACConfig.pm line 672.
Segmentation fault (core dumped)
mclark@mikec-alien:~$ sh: 1: kill: No such process

I do see a /home/mclark/.config/pac directory but no config file yet. Just the following five directories:

mclark@mikec-alien:~$ ll .config/pac/
