latvian together with titlesec cause error

[leomayer]

I've encountered an issue and it was very well analysed. The MWE

\documentclass[a4paper,11pt]{article}
\usepackage[latvian,shorthands=off]{babel}
\usepackage{titlesec}

%%% ensure \chapter passes the \ifx\chapter\undefined test
%\let\chapter\undefined
%%%

\begin{document}
    \begin{figure}[!htbp]
        \caption{Sample text}
    \end{figure}

\end{document}

Changing to e.g. french the code compiles without problems. Perhaps the issue might appear in other languages as well?

Fixed on the titlesec side. It remains to be fixed on the babel-latvian side.

Fix just submitted to CTAN.
