For future users, I installed libepoxy0 (1.3.1-1ubuntu1) from zesty manually by downloading the right deb for my architecture (https://packages.ubuntu.com/zesty/libs/libepoxy0), and then installing with "dpkg -i". It seems that the newer package in zesty has a fix for the underlying bug. It appears to work fine now, no more segfaults when launching synaptic (or other GTK3 applications) over X-forwarding!
