That is intended behavior, evince with USE=nsplugin breakes konqueror. See bug 544630
(In reply to Andrei Slavoiu from comment #1) > That is intended behavior, evince with USE=nsplugin breakes konqueror. See > bug 544630 Could you be a little bit more elaborate. Why breaks the gnome pdf viewer the kde browser? And what is the best way to solve the issue, to remove the nsplugin USE flag from evince? I suppose doing this, evince can't follow embedded links in pdf files.
The details are in the bug I linked. USE=nsplugin causes evince to build a plugin for embedding PDF documents into browsers, not sure if it changes anything in the standalone app.
You need to disable the nsplugin for evince (once you do that, the links will be opened by a separate evince window) *** This bug has been marked as a duplicate of bug 544630 ***
