I modified his bug report, to make it clearer.

I can also confirm this crash with LyXWin 1.3.3.

As the full row is highlighted, LyX doesn't know where to insert the new
character in the matrix. Because normally if one highlights characters and press
a character key, the highlighted characters are replaced by the new character.
To avoid this, LyX should delete all entries of the row and fill the new
character to the first box of the row.
