Zanata generates URLs with a duplicate /zanata

I am currently upgrading Zanata from 4.0.0 to 4.4.5, and I'm noticing a bug regarding the generation of URLs.

I have the following configuration :

Server URL
http://lab-zanata/zanata

When I open my profile the first time using the side nav it works (http://lab-zanata/zanata/profile/view/fplante), but if I choose again profile, glossary or languages, the URL has an extra /zanata in it (http://lab-zanata/zanata/zanata/profile)

This was working in 4.0.0 so I'm assuming this is a new regression.
