Alternatively:

The same problem

I suppose this is a different problem, because in LaTeX, text sub/supscripts
are different from math sub/supscripts:

math:  x_i
text:  x\textsub{i}

LyX assumes the "text" to be converted to math with ^M to be LaTeX-math
source code (which is a common way to store mathematical content in 7-bit
ASCII format).
