First of all, the first frame works just fine for me.  Line breaks are
preserved.  However, I do know that in the past I have had problems with
alltt environments in beamer.  I tend to use one of the algorithm
packages instead.

Your second frame leads to an error because the \in and \leftarrow are
not in math mode.  Because your LaTeX code is explicitly in an export
LaTeX environment, org doesn't do its usual magic with LaTeX entities so
you need to put the maths delimiters yourself:

When in doubt, export to LaTeX (C-e l b) and have a look at the
LaTeX.  Also then run pdflatex yourself on that LaTeX code to see what
errors come up.
