[Bug] Accents in math mode

[Thomas Steffen]

Hi,

I discovered a bug in math mode. If you enter (in math mode)

\tilde \overline{x 

you actually get 

\overline{\tilde\{x}}

The same happens when a document is read, where the above sequence
appears. Since there is no LaTeX limitation concerning either form, I
believe this to be a bug. (It is possible to do the trick by using a
macro, but that leads to rather frequent crashes.)

I am using LyX 1.1.5fix2 (debian testing on x86), can any one verify
the bug on 1.6?
