It is indeed. And usually \section commands are recognized by reLyX,
so it seems something threw it off before this line.

The reason is, that there is not Style for the "frame" environment in
the standard beamer.layout file. Instead, there is the "BeginFrame"
style that translates to \lyxframeend{}\lyxframe.

I propose an alternative beamer.layout file without all these
"lyxframe...". This is somewhere down on my TODO list (after getting

As a start, you could try to copy beamer.layout to your \$LYXDIR/layout/
seminar.layout, not tested):

Style Frame
LatexType               Environment
LatexName               frame
NextNoIndent            1
Margin                  Static
LeftMargin              N
ParIndent               ""
TopSep                  0.4
LabelType               Top_Environment
LabelString             "Landscape Slide:"
End

Then, re-try the import. If this helps a bit, we can try to devise a
more standard beamer layout.
