Create a math table, say 4x4. Write something in the first (say three) cells. Go to the begin of the very first cell. Hit Backspace. -> The table collapses. Not very nice, although 'undo' still works Add something in the collapsed cell. -> Undo produces an empty cell. -> Undo again segfaults. (is caught by LyX, but anyway...)
