Hi,
here is an other bug in lyx2lyx : suppose, with lyx-1.5 you define a
command \mytextrm to be \textrm
and type, in a math formula \mytextrm{équicontinu}. This is well
traduced in latex by lyx-1.5.
But if you open the file with lyx-1.6 then the latex output is (for
example):
$F\,\mytextrm{\acute{e}quicontinu}$
which is invalid and gets a latex error.
(lyx-1.5 traduce it to : $F\,\mytextrm{équicontinu}$ which is correct)
Here is, attached, an example

Description: application/lyx
