I somehow have the feeling that it could be a kernel bug, as I have other
strange things happening as well which also could be caused by a kernel
bug. As I am planing to upgrade to El Capitan today or tomorrow, I will
wait with further test until then and let you know.
Another pointer towards the kernel: the error only occurred after a
holiday, which resulted in the upgrade of the OS, emacs, packages, ...
So I could not pinpoint what caused it.

This was already the third session, as it also did not make sense to
me. Also: continued "continue" resulted in exactly the same error
message and no continuation.
OK - I will then upgrade and report back in a few days time to see if
the upgrade solved the problem.
If it was kernel, I am really sorry for your wasted time,
I will report back then,
Thanks a lot,
Rainer
