I just checked, and the prior version of libspectre (libspectre1_0.2.7-2ubuntu1_amd64.deb), located at:
https://launchpad.net/ubuntu/trusty/amd64/libspectre1/0.2.7-2ubuntu1
renders the eps files correctly. Thus the bug was introduced in the change from -ubuntu1 to -ubuntu1.1 as a result of trying to fix Bug #1242678.
