git-gui ignores core.hookspath

Hello,
I’m running on 

$ git --version --build-options
git version 2.11.0.windows.3
built from commit: e11df2efb3072fe73153442589129d2eb8d9ea02
sizeof-long: 4
machine: x86_64


and trying to use core.hookspath with git-gui in my local repository in windows cmd shell 
$ cmd.exe /c ver
Microsoft Windows [Version 6.1.7601]
I have defined a pre-commit hook and set the path to it using core.hookspath, but when commiting in git gui it is not considered. 


Commiting directly on the cmd shell using git commit -a -m "ndkfnj" it works perfectly.

Thanks for any advice or bugfix
