Nevertheless, I'm not the only developer/user, and others might be interested 
in this, too, so please always send mails as this one to one of the lists. It's

Funny that you found that just now: we discovered this bug just last week and I 
fixed it yesterday. If you want the fix but don't want to use a git version, 
just remove the " + 1" in your code.
