### Please describe the problem.

"Git annex sync" stopped working when syncing my NAS to my Laptop, it just eats up all the memory on the NAS without any result. When running the debug mode I found out that it stops working when it tries to run "git-annex-shell 'configlist' 'mygitannexfolder'".
That's the first command to be run on the NAS over ssh.

I traced the problem down and the following command also won't work without any output just eating up all memory:
ssh myuser@mynas "git-annex-shell 'configlist' 'mygitannexfolder'"

But when I log in to the NAS and run the git-annex-shell script inside the .ssh folder with exactly the same command, it works perfectly and returns the uuid and so on.

### What steps will reproduce the problem?
Execute on PC (doesn't work, just uses all memory and crashes): ssh myuser@mynas "git-annex-shell 'configlist' 'mygitannexfolder'"
Execute on NAS (should work): ./.ssh/git-annex-shell "git-annex-shell 'configlist' 'mygitannexfolder'"
