Version:           unspecified (using KDE 4.8.0) 
OS:                MS Windows

Because the web-form would not let me specify it, I am use Kile version 2.9.60 on Windows 7 (64-bit).

Kile chokes every time I add \label{some_label} to a math formula inside \begin{align} ... \end{align}. Curiously, it does not crash for the (outdated) eqnarray-environment.


Reproducible: Always

Steps to Reproduce:
Just compile this short example and it crashes

\documentclass[a4paper,10pt]{article}

\usepackage{amsmath}
\usepackage{amssymb}

\begin{abstract}

\end{abstract}

\section{}
\begin{align}
  A\mathbf{x} &= \mathbf{b} \label{eq}
\end{align}

\end{document}

Actual Results:  
Kile crashes, bug report application opens.

Expected Results:  
A compiled PDF-document.
