What version did you install/how did you install it?

I can't reproduce this, which either means the input you got was mangled slightly when pasting it in (I edited your post to make it a bit clearer. Don't forget that issues are first processed by github markdown, so using codeblocks is useful.) or we've fixed this already and just need to release a new version

Closing until we get more info. Please fell free to reopen.
