Conflicto de Beamer, Babel y Tikz

Question

Estoy preparando apuntes de conferencias en turco y tengo un diagrama para el procedimiento de modelado matemático. Pero yono puedoproducir un buen resultado para el siguiente código. Cuando elimino los tres primerospaquetes, obtengo el resultado deseado. Sin embargo, necesito conservarlos en mi documento. ¿Me ayudarías en esta dirección?

\documentclass[10pt,notheorems]{beamer}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[turkish]{babel}

\usepackage{tikz}
\usetikzlibrary{positioning,shapes,arrows}

\hypersetup{bookmarksdepth=4,bookmarksnumbered=true,bookmarksopen=true}

\usetheme{Warsaw}
\usecolortheme{seahorse}

\begin{document}

\begin{frame}[fragile]{}{}

\begin{figure}
  \centering
  \begin{tikzpicture}
    \node (rwp) [draw,fill=blue!20,text centered,minimum height=2em,rounded corners] {Ger\c{c}ek ya\c{s}am problemi};
    \node (mm) [right=2cm of rwp,draw,fill=purple!20,text centered,minimum height=2em,rounded corners] {Matematiksel model};
    \node (mc) [below=2cm of mm,draw,fill=green!20,text centered,minimum height=2em,rounded corners] {Matematiksel \c{c}{\i}kar{\i}m};
    \node (rwq) [below=2cm of rwp,draw,fill=red!20,text centered,minimum height=2em,rounded corners] {Ger\c{c}ek ya\c{s}am tahminleri};
    \path [draw,->] (rwp.east) -- node [above] {Form\"{u}lasyon} (mm.west);
    \path [draw,->] (mm.south) -- node [right] {\c{C}\"{o}z\"{u}m} (mc.north);
    \path [draw,->] (mc.west) -- node [below] {Yorum} (rwq.east);
    \path [draw,->] (rwq.north) -- node [left] {Kontrol} (rwp.south);
  \end{tikzpicture}

Babel define varias abreviaturas para simplificar la entrada de caracteres especiales, lo cual es muy útil para ingresar letras, pero a veces esto causa conflictos con otros paquetes. Por suerte tikztiene la biblioteca \usetikzlibrary{babel}que soluciona el problema.
