Fixing this bug was actually easy: But it is frustrating, that I cannot reproduce such bugs on my on XAMPP development environment. I already added following line to my.ini:
sql-mode="STRICT_ALL_TABLES,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

But it seems to have no effect at all. :(
