If on a multilingual installation of ezpublish 4.0.1 you try to switch to another language, then click on an article "e.g. Lyon, a european metropolis", then click back on english, it will try to fetch the foreign url, resulting in a module not found error.

It requires a fetch which looks for the correct URL, according to the language.

Steps to reproduce

• Install eZ Publish 4.0.1
• Select English (united kingdom) and French as languages
• Open the homepage
• Click on Fre in the top left corner
• Click on Lyon, une metropole europeenne
• Click on Eng
• See the module not found error
