commit 9f95a4b24da3cd50eba78ffecaf00c2379d63497
Author: Jan-Marek Glogowski <glogow at fbihome.de>
Date:   Fri Apr 22 04:48:08 2016 +0200

    Disable font dependent tests when missing fonts
    
    A (very) few tests depend on correct MS metric compatible fonts,
    like Calibri, Arial and Times New Roman, and fail if these are
    substituted with incompatible fonts. Disable failing asserts, so
    we'll at least test loading the documents.
