+Subject: [PATCH] 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.
