On installing said version, build 13499, my Avast AV 8.0.1489, virusdef 130621-3, fired an alarm on the file spatialrelationshipfactory.dll and put it in the quarantine.
Avast says the reason is Win32:Evo-gen nsusp]
The file date for the file was 2013-06-05 12:15:16
Has anybody else seen this? Most likely, the alarm is false.
