Hi,

I have submitted a patch for review:

    https://gerrit.libreoffice.org/1860

To pull it, you can do:

    git pull ssh://gerrit.libreoffice.org:29418/core refs/changes/60/1860/1

bnc#798271: Don't delete the PropertyMapEntry instance prematurely.

When using comphelper::PropertyMapEntry array to create a UNO property
set, we need to make sure we keep this instance while the property set
object is alive, else it would cause a very hard-to-debug problem down
the road...

In this particular case, the aExportInfoMap array instance was destroyed
when it went out of scope, but the xInfoSet which references it was used
afterward.
