Eventually it may be a question the the version of libevince installed
on your machine. (In fact you could test 
http://www.denemo.org/~rshann/denemo_2.4.x.AppImage
which has a libevince built in)

But to narrow it down I would run

gdb denemo


b action_for_link

r

and then try clicking on a link in the Print View.

(I'm guessing you are familiar with gdb? If not ask!)
