Date: Fri, 16 May 2014 15:33:38 +0200

Hello.

This commit introduced the error, I suspect the error is present on all 
ports:

revno: 116927
committer: Dmitry Antipov
branch nick: trunk
timestamp: Wed 2014-04-02 17:24:19 +0400
message:
  * font.c (font_list_entities): Do not add empty vector to font cache.
  (font_matching_entity): Likewise.  If matching entity is found, insert
  1-item vector with this entity instead of entity itself (Bug#17125).
