[PATCH] Change in core[libreoffice-4-0]: Resolves: fdo#59183 Copy 4 or more slides then crash

Hi,

I have submitted a patch for review:

    https://gerrit.libreoffice.org/1726

To pull it, you can do:

    git pull ssh://gerrit.libreoffice.org:29418/core refs/changes/26/1726/1

Resolves: fdo#59183 Copy 4 or more slides then crash

regression from 17afe4cea7e01aef1e5270cc09f438bc6fde3211 which is totally
forgivable as its riddled with asserts that suggest there should be no
out-of-bounds accesses and there probably shouldn't and those queries are
possibly bugs. But double-checking 3-6 it is the case that non-existant pages
were queried for in that version too, so return NULL on out-of-bounds
like the original pre-stl conversion code did.

(cherry picked from commit 63de2b8f1493f24669c78df3bc2d48d13528bd9f)
