yes, the Evince library is supposed to emit a signal when you click on
a link, and Denemo has a signal handler connected for it

  g_signal_connect (G_OBJECT (Denemo.printarea), "external-link",
G_CALLBACK (action_for_link), NULL);

at  printview.c:2779

so breaking gdb on the function action_for_link would establish that
the signal is not being emitted (assuming line 2779 was executed!).
