You have some blank lines in your tikz code. Remove them. A blank line has a special meaning in TeX and that is confusing TikZ.

Without the blank lines, it works fine.
*Took me a while to figure that out myself. I never use TikZ and thought it would take better care of that.

Dear Johannes,

Thank you very much, let me work on it.
