70959 - browser crashes when tab+spacebar is used to close composer window

Status: RESOLVED DUPLICATE of bug 71141

(Core :: XUL, defect)

Description

[shrirang khanzode]

Seen on today's trunk 

steps:

1 Open 2,3 composer windows and type some test in each
2 Now close one window using the 'x' button on top right
3 When the dialog comes up asking you to save, don't save,cancel (with SAVE 
highlighted), use TAB to shift focus to 'Don't Save' button and press spacebar.
4 If you are lucky , u will see the crash there itself, however, if u do not, 
just repeat step 3 on the other two pages and you should see this.
