I have Intellij 15 and a Github account, and I\'m trying to unite the two. I went into settings -> Version Control, and added Github with the Host and username and password
I was having this issue until I set the SSH-executable option to use Built-in
SSH (just like you have). This immediately solved my problem and I wasn't getting the error anymore.
Further options I am using include:
C:\Program Files\Git\bin\git.exe
Apart from these 3 options, my settings look exactly like yours. I am running windows 10 64bit and my version of IntelliJ is 2016.1.1
