[Libreoffice] [REVIEW] Fix crash when selecting target after inserting hyperlink to database document

Hi all,

https://bugs.freedesktop.org/show_bug.cgi?id=36545

This one is a trivial one, please see the attachment.  All in all, just

Please check, sign-off, and push to libreoffice-3-4

Regards,
Kendy
