This is very strange.  What does the LaTeX code generated look like for
this case?  In my case, I get:

\begin{frame}[label={sec:org4b25942}]{}
some text for the slide
\end{frame}

Maybe have a look at your write-file-hooks and write-file-functions
variables to see if there is some invocation that strips whitespace?

You may wish to use the whitespace package (for a little time) to see
when a space at the end of headline disappears.  The whitespace package
is part of Emacs.
