Thank you!
Resending from the admin site shows empty email fields, too.
I had a look at the database (using phpmyadmin), there are the fields empty as well.
Names with german Umlaut, apostrophes etc. works fine so far.
Problem is that I cannot reproduce the error. I tried it with two different installations on two different servers. Would it make sense to try to change the php version? (I am not really familiar with php…)
