For DejaVu, I believe this is the bug reports I submitted here:
https://bugs.freedesktop.org//show_bug.cgi?id=26940
https://bugs.freedesktop.org//show_bug.cgi?id=26941
See also
   https://bugs.freedesktop.org//show_bug.cgi?id=28475
marked as a dupe of 26941.  I don't believe anything has been done on
either of these bug reports.
