If a note from
https://cgit.freedesktop.org/libreoffice/core/commit/?id=dc06c8f4989fc28d0c31ebd333e53dfe0e0f5f66
applies,
then you can't fix it until we support Ubuntu 14.04 (due to its old gcc
version):

Turns out the std::move can only be dropped if the compiler has a fix for
CWG1579. For GCC
that's the case starting with GCC 5.1
