[REVIEW 3-5] Fix for fdo#46942.

[Kohei Yoshida]

Hi there,

I'd like to have the attached patch applied for the 3-5 and possibly for
the 3-5-2 branch as well.

It fixes

https://bugs.freedesktop.org/show_bug.cgi?id=46942

It's actually a very old regression, as the responsible commit goes back
to May of 2011.  But it was only recently discovered & reported.

To me this is a very safe change, caused by simple oversight.  I'd like
to have this pushed to 3-5, and possibly 3-5-2 if people agree.

Master has the same fix already, but because I did some cleanup before
fixing the bug, it made my fix non-backportable without some adjustment.

Anyway,

Kohei
