LyX 2.0.5.1 Ubuntu 12.10

I am trying to import and run a LateX file in LyX. The problem arises
when I have a figure with subfigures.  A single figure processes with no
problem.

The file is fine in LaTeX but chokes in Lyx. I have seen a few
references to the problem on the internet but I have not seen any
solution that makes sense to me. The closest thing seems to be
http://tex.stackexchange.com/questions/19946/missing-number-treated-as-zero
but since it is referring to a LaTeX problem not a LyX problem it does
not help.

The original file produces 14 pages of pdf output with 12 figures both
single and multiple layouts with no problems and so I thought I'd see
how well it imports into LyX

I have attached a stripped-down .tex file and two png files that I am
using as a test case. I imported the .tex file into LyX using File 
Import  Latex(plain)...

The error message is :
Missing number, treated as zero.
Illegal unit of measure (pt inserted).
Missing number, treated as zero.
Illegal unit of measure (pt inserted).

A number should have been here; I inserted `0'.
(If you can't figure out why I needed to see a number,
look up `weird error' in the index to The TeXbook.)

When I look at the LaTeX Preamble in LyX I get:
\usepackage[hang,flushmargin]{footmisc}\usepackage[english]{babel}
\usepackage[font={small,it}]{caption}\usepackage{subcaption}\author{John
the Toucanite}
\title{The Scholar}

My LaTeX preamble is

\usepackage[hang,flushmargin]{footmisc}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[english]{babel}
\usepackage{graphicx}
\usepackage[font={small,it}]{caption}

\date{}

I tried pasting the LaTeX preamble into LyX and removed
\documentclass[12pt]{article}
\usepackage[margin = 4.0 cm]{geometry}
since they were giving me conflicts.

I still get the same error.







Indeed, \begin{subfigure}[h]{0.5\textwidth} isn't parsed correctly by 
tex2lyx: It is put into ERT except that [h] ends up outside of ERT. On 
LaTeX output, LyX tries to protect the square brackets by outputting 
{[}h{]}, but this is incorrect LaTeX.


Just checked and this bug is also in the development version LyX 2.1
