Delivering wrong theme when Symfony2 has to build up the cache

[ebi]

For some reason on the very first request, after cleaning the cache we always get the default theme. That is either a bug in the cookie detection or the activetheme.

Experiencing same issue. Debugged till here: https://github.com/liip/LiipThemeBundle/blob/master/Assetic/TwigFormulaLoader.php#L55
A line above causes theme to be changed when loading something related to Assetic, and never sets active theme back.

Quick fix: you should make so webserver env configs do not have

liip_theme:
    assetic_integration: true
