show stopper in xfwm4

[edscott wilson garcia]

Hi Olivier,

I came across a showstopper in xfwm4. On clicking the [-] from the title
bar, I doubleclicked simultaneously with the mouse move and the window
did not close nor did the menu appear. Xfwm4 went into an endless loop.
Output on terminal on which X was running was:

Max = 1249

printed about twice a second.
Apparently the maximize menu entry got a signal before it was supposed
to and xfwm4 looped trying to figure out the maximization borders. It is
very rare and difficult to reproduce, but it will force an X shutdown.

regards,

Edscott
