Great catch! Yup, it seems to be the same logic. It should be pretty
safe because it just comes through the list in sequence instead of
starting from the beginning each time. It works fine.

I have pushed it into 3-5, see
http://cgit.freedesktop.org/libreoffice/core/commit/?h=libreoffice-3-5&id=43b48f05e5aa3359a0227550b9a5c88851a582d2

It will be in 3.5.3-rc1.
