I got no error message with LyX 1.1.4pre1, but \mathfrak{g} and
\mathbb{R}
is only standard g and R letter, \boldsymbol{\alpha} is correct bold
alpha.

in mathmode <alt>M-m all works well. Look at the attatchment. 
Have you installed the LaTeX ams-package?

\layout Standard

Although I have activated the radio button of AMS math at the Layout->Document
 menu I can not been able to follow what the UserGuide.lyx suggets.
 In particular, both 
\latex latex 

\backslash 
mathfrak{g}
\latex default 
 and 
\latex latex 

\backslash 
mathbb{R}
\latex default 
 give an error message.
 
\latex latex 

\backslash 
boldsymbol{
\backslash 
alpha}
\latex default 
, which does not seem to require the AMS extentions is working as expected.
 Can you advise what is the problem? 
\latex latex

\begin_inset Formula \( \mathbb {R}y=x\, \mathfrak {g} \)
\end_inset

All works well.
