Thank you very much, Max. By further investigating the problem I had, I tried to export the following snippet:
--- ** Example *** Temperature control :B_example: :PROPERTIES: :BEAMER_env: example :END: Let us make a simple example of temperature control. #+attr_latex: :float t :width .5\textwidth [[file:room1-crop.pdf]] --- When exported, this produces the following : --- \begin{frame}[label={sec:orgb828ded}]{Example} \begin{example}[Temperature control] \footnotesize Let us make a simple example of temperature control. \begin{t} \centering \includegraphics[width=.5\textwidth]{room1-crop.pdf} \end{t} --- Which is of course not what I want. Notice the \begin{t} ... \end{t}. If I remove the ":float t" option : --- ** Example *** Temperature control :B_example: :PROPERTIES: :BEAMER_env: example :END: #+begin_export latex \footnotesize #+end_export Let us make a simple example of temperature control. #+attr_latex: :width .5\textwidth [[file:room1-crop.pdf]] --- The exporter produces --- \begin{frame}[label={sec:org5a5b3f6}]{Example} \begin{example}[Temperature control] \footnotesize Let us make a simple example of temperature control. \begin{center} \includegraphics[width=.5\textwidth]{room1-crop.pdf} \end{center} --- Which is certainly more correct. There is no mention of this behavior in the manual, and in the past the ":float t" option worked as expected. In facts, I have tens of org-mode documents for my slides, all containing the ":float t" option, and now they are all exported incorrectly. Is this a bug, or has the syntax changed in a way that is not documented yet ?
