Option clash

[Pedro Tejedor]

Dear developers,

I downloaded and compiled recently lyx 1.3. It produces an error when I

- choose interline space to be one and a half
- use dvips option
- use a table with a figure in one cell, and a rotated text in the other
- try to compile it

the error message says:

LaTeX Error: Option clash for package graphicx.
\usepackage
{setspace}
The package graphicx has already been loaded with options:
[]
There has now been an attempt to load it with options
[dvips]
Adding the global options:
,dvips
to your \documentclass declaration may fix this.

It also happens if I have another table float rotated near the table with a figure on it.

If I deselect the "dvips" option and choose default the file compiles without error, but I don't know the consecuences of not choosing dvips.

Have I done something wrong, or is it a plain little bug?

Thankyou

Pedro
