The crash is inside libnss_myhostname, most likely na upstream bug that has to be reported to libnss. After reporting the bug there please add a link here.
I opened a bug at https://bugs.freedesktop.org/show_bug.cgi?id=87634 for the issue.
It turns out that the "discovery via DHCP not supported" line is in the terminal output when the assertion is hit and when it isn't so this does not seem to be related after all.
