Should not be invoked error when publishing


VS 2013

Create bottle project
Create virtual env
Install bottle
Publish to Web Site
I clicked on Preview and waited to get the file list (don't know if that makes a difference or not)
I clicked Publish

Publish aborts, the output window shows:
------ Publish started: Project: BottleWebProject1, Configuration: Release Any CPU ------
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Python Tools\Microsoft.PythonTools.Web.targets(606,5): Error : Should not be invoked during up-to-date check
