[REVIEW 3-6] fdo#53337 crash in search in help

[Caolán McNamara]

This is reported on the vanilla MacOSX and Linux build binaries, but
doesn't happen locally for more recent tool chains. My guess is that its
visibility related and missing typeinfo so the exception doesn't get
caught where it should be.

So
http://cgit.freedesktop.org/libreoffice/core/commit/?id=715e2109f60b016f661d98a59aef674e0951a2ad
should fix that.
