Crashes both jquery-1.3.2 and 1.4 alpha 2 in IE 8 and Webkit. I know it's bad syntax, but ; should be ignored by parser. It was pretty hard to guess where the bug was :)

jquery-1.4a2 gives

"Line: 4140

Error: Invalid property value."

EXAMPLE:

var some_css = {

'background-color' : '#f0f0f0;',

'font-weight' : 'bold',

'color' : '#ff0000'

}

jQuery('.myselector').css(some_css);

This works ok (no ; ):

var some_css = {

'background-color' : '#f0f0f0',

'font-weight' : 'bold',

'color' : '#ff0000'

}

jQuery('.myselector').css(some_css);
