Thank you very much for your email.
I just tried this again but could not reproduce it either.
I guess it just happened to a very particular message in my inbox.
I was probably quite unlucky that my first try was on such a
peculiar message.
Now I couldn't remember what message I was looking at and I cannot find it
anymore.
I'll report back if I see the problem again.
