math parser warning "unusual contents found" in examples/xyfigure.lyx

[Scott Kostyshak]

I get the following on my terminal when I open the file with LyX 2.1dev:

unusual contents found: [xymatrix [grid [row [cell [char A
mathalpha][macro ar][char [ mathalpha][char d mathalpha][char ]
mathalpha][macro ar][char [ mathalpha][char r mathalpha][char ]
mathalpha][char   mathalpha]][cell [char   mathalpha][char B
mathalpha][macro ar][char [ mathalpha][char d mathalpha][char ]
mathalpha][macro ar][char @ mathalpha][block [char - mathalpha][char -
mathalpha][char > mathalpha]][char [ mathalpha][char d mathalpha][char
l mathalpha][char ] mathalpha][char   mathalpha]]][row [cell [char C
mathalpha][macro ar][char @ mathalpha][block [sub [par][char (
mathalpha]][char - mathalpha][char > mathalpha]][char [
mathalpha][char r mathalpha][char ] mathalpha][char   mathalpha]][cell
[char   mathalpha][char D mathalpha][macro ar][char @ mathalpha][char
/ mathalpha][sub [par][char 1 mathalpha][char p mathalpha][char c
mathalpha]][char / mathalpha][char [ mathalpha][char u mathalpha][char
] mathalpha][char   mathalpha]]]]]

Any idea how to fix?
