Clicking on URL fails when Chromium is the default browser

[Salem]

When I open a PDF with some url links on it, I cannot open them through Evince (it does not launch a new browser window/tab). This only happens when Chromium is the default web browser. If I set the default to Firefox, the links open correctly.

If I open the pdf from the terminal, once I click on a link I get the following message:
/usr/lib/chromium-browser/chromium-browser-sandbox: error while loading shared libraries: libpthread.so.0: failed to map segment from shared object: Permission denied

I'm not really sure if this is a problem from Evince or Chromium, but other applications which also allow to open links on click work well with Chromium.

How to reproduce:

* Having Chromium as default browser;
* Open any PDF with an url link on it (http://...)
* Click on the link or left click -> "Open URL"

Expected behavior: after clicking on an URL, a browser window should open.
What happens: none window appears; error message on terminal.

Ubuntu release: Ubuntu 12.04.2 64bit
Evince version: 3.4.0-0ubuntu1.5
