System.NullReferenceException: Object reference not set to an instance of an object #7620

NuGet Version: 4.9.1.5694 (CLI)

For the record version 4.7.1 behaves the same way.

I tried to make a custom package out of FSharp.Data (https://github.com/fsharp/FSharp.Data) -- I added my nuspec and key -- and then I executed:

c:\tools\nuget pack FSharp.Data.fsproj -includereferencedprojects -prop configuration=release -verbosity detailed

As the result I got exception:

Object reference not set to an instance of an object.

My point is, even if there is something wrong, the result should be like "detected recursive dependencies" and not a raw exception.
