I reproduced this bug with the poppler-glib-demo included with poppler with the
same PDF file.

What I do reproduce the crash is I run the poppler-glib-demo included with
poppler in poppler/glib/demo, go to Links, go to page 4, click "Get Links" and
get a segmentation fault with the same backtrace. This is with poppler-0.14.2
which is 4 commits back.

Here is the backtrace, which is like the other one attached:


poppler-0.14.2.real/glib/demo/.libs/poppler-glib-demo ../../../microtype.pdf
[Thread debugging using libthread_db enabled]
