Bug Description

On Ubuntu 14.04, with
Chromium Version 34.0.1847.116 Ubuntu 14.04 aura (260972)
provided by: 34.0.1847.116-0ubuntu2

Chromium can successfully search here:
https://duckduckgo.com/

But not here:
https://duckduckgo.com/html/
(Enter a query, press Enter, and you will get a blank page.)

Firefox can search at both urls, as can Chromium 28.x on Ubuntu 13.04.

I wonder if apport will give you sufficient information to reproduce this bug. I have discovered the bug is more complicated than it first appeared. Here is how to reproduce it.

1) Boot ubuntu-14.04-desktop-amd64.iso from a USB stick.

2) Install and run chromium-browser

3) Manage search engines, add a new search engine:

ddg ddg https://duckduckgo.com/html/?q=%s

4) Make the new search engine the default.

5) Press ctrl+t to get a new tab, type "testing" in the url/search box, press enter and get a page of results.

6) Click on the green magnifying glass to search again. You will get a page without any search results.

7) Switch the default search engine to Google. Now the duckduckgo.com/html/ page will search correctly and display results.

8) Switch the default search engine back to "ddg", and the problem reappears.
