sdk: Error "path1 cannot be null" when invoking "dotnet run" on Linux when HOME is not set

Steps to reproduce

On Linux, invoke “dotnet run” when HOME is not set. My specific scenario was invoking “dotnet run” from an Upstart job.

Expected behavior

Works correctly or displays friendly error message.

Actual behavior

System.ArgumentNullException: Value cannot be null.
Parameter name: path1

I’m seeing a similar issue with CLI 1.0.0-rc4-004757, though it appears the root cause has moved from the CLI to NuGet.

My upstart script contains the following:

env NUGET_PACKAGES=/home/<username>/.nuget/packages
exec /home/<username>/.dotnet/dotnet run -p /home/<username>/<project>.csproj

The call to dotnet run fails with the following callstack:
