2.15.2 core dumping in rrd updates

Ever since updating to 2.15.2 I'm seeing consistent and repeatable  
core dumps with one of my configurations.  But only one, and it's  
confusing me.  Someone got any idea what else to look for?

$ /usr/local/bin/mrtg --debug="cfg,snpo,log" core2.cfg
(first 100 lines or so)
--snpo: SNMPfound -- 'ManagementEthernet 0/0', 'undef',  
'ManagementEthernet 0/0', 'undef'
