Well, I'm not a magit user, so I cannot debug magit itself. But you
might check first, which git version you're using via Tramp. First check
the command to be called:

C-h v magit-git-executable

The result shall be "git". Next, open a remote buffer, say dired in
"/ssh:address@hidden:", and apply the following shell
commands:

M-! which git
M-! git --version

I suppose that magit uses both synchronous and asynchronous processes,
so you shall check the results for asynchronous shell commands as well:

M-& which git
M-& git --version
