TOC jump to subsections does not work, can only jump to numbered lines in amsart

[arjunkc]

Here is a working minimal example

\documentclass{amsart}
\input{/home/arjun/Templates/preamble.tex}
\usepackage{natbib}
\usepackage{todonotes}
\usepackage[normalem]{ulem}
%% some custom commands
\newcommand{\K}{\mathbb{K}}
\newcommand{\lions}{Lions and Souganides}
\newcommand{\SET}{subadditive ergodic theorem}
\newcommand{\FPP}{first-passage percolation}
\newcommand{\FPT}{first-passage time}
%\newcommand{\tr}{\textrm{tr}} % for writing trace inside equations
\renewcommand{\limsup}{\overline{\lim}}
\renewcommand{\liminf}{\underline{\lim}}
\newcommand{\deltaapprox}{$\delta$-approximation}

\subsection*{Notes}
\subsection*{Problem Definition}
\begin{enumerate} 
  \item Wed 01/02/2013 \label{item:generalized-discrete-problem} Write down the version of the problem that you want to deal with. It needs to have a natural subadditive structure at the core of the problem.   
  \begin{itemize}
    \item What are the assumptions on the weights $l(x,\alpha)$. It seems that one needs to have weights bounded below (not necessarily nonnegative). 
    \item Penalization should work. The assumptions might not be uniform in delta, in this case.
  \end{itemize}
\end{enumerate}
\end{document}

The TOC window shows

1   \tocsection{To do
    \tocsubsection{}{Notes
    \tocsubsection{}{Problem Definition

<Esc>/q: close
<Space>: jump
<Enter>: jump and close
s:       hide numbering

But it cannot jump to any of the subsections. It gives the following error:

Error detected while processing function <SNR>47_TOCActivate..<SNR>47_TOCFindMatch..<SNR>47_TOCFindMatch
..<SNR>47_TOCFindMatch:

Could not find: \\subsection\_\s*{.*{Notes}

Is it the amsart class that's giving these issues? I saw a similar issue with beamer

The issue is fixed completely by using \documentclass{article} and recompiling.

same error here using a koma-report class (\documentclass{scrreprt})
