Well, I noticed, that I had a bug in  post-receive hook, so here is the 
fixed one:

export GIT_WORK_TREE=/domains/site/test-workdir/
export GIT_DIR=/domains/git/site-bare.git/
git checkout -f

However, the problem still remains.

Also GIT_TRACE=1 did not help, there was no any useful info.

I will test your suggestion(s) to debug the problem.
