If the bug is not reproducible, we can close it as such.

No, but it should be easy to add this: see send_to_emacs in
emacsclient.c.  You can also see what was received by the server if
you set server-log non-nil: then the server will log the received
directives in the " *server*" buffer.

Not sure how this would help you, given the description of the
original problem, though.  Am I missing something?
