1.6.5 mathed crash

[Joost Verburg]

Hi,

I was just typing some math and 1.6.5 crashed with the following assertion:

lyx-1.6.5\src\support\lassert.cpp(21): ASSERTION pos < size() VIOLATED 
IN lyx-1.6.5\src\mathed\MathData.cpp:56

Does anyone know whether this may be related to a known bug (I couldn't 
find this assertion in trac)? I don't know yet how to reproduce, maybe 
the assertion gives a clue.

Regards Joost
