Browser: TYPO3 without PHP

tt_address isn't localised which is why there is no data output. Browser stops at line 2618 in class.tx_browser_pi1_localisation.php.
Commenting out this line all works fine.

• TYPO3 4.7
• tt_address 2.3.4
• browser 4.9.1
• typoScript:
  

  config {
    sys_language_mode = content_fallback
    sys_language_overlay = 1
    sys_language_softMergeIfNotBlank = 1
  }
