In last 2 previous versions it appears each 4th or 5th time, not
equally repetitive.

I am not sure if I am using correctly git checkout to try earlier
version. Today I tried it for third time, back in time, and this
emacs-repository-version d715e6d8c6a7f3507f4faca0961ac87d58fbfab8 is
still having the same problem.

What I do, I read email by using mutt, then I hit r to reply email,
including your emails, and I can see the notice from emacsclient on
console, but the graphic frame is dropped, and later I see the bug in
Emacs. Was not there before we started conversation and in the version
I used last.

I can just say that in this version
d715e6d8c6a7f3507f4faca0961ac87d58fbfab8, the bug appeared one time
only out of 30-40 times.
