Crash with $().attr("-moz-border-radius","6px") or "-webkit-border-radius"

Crash with $().attr("-moz-border-radius","6px") or "-webkit-border-radius"

Greetings,
I'm using 1.3.2 and I've discovered that if I attempt this line:
$("#messagebox").attr("-moz-border-radius","8px").attr("-webkit-
border-radius","8px");
Bad things happen. Specifically, JS stops processing and the browser
(Chrome in this case, but the 'crash' happens in all browsers I've
tested.) reports:
Uncaught Error: INVALID_CHARACTER_ERR: DOM Exception 5 -
jQuery-1.3.2.js (line: 1026)
Same thing occurs in the minified version (but on a different line, of
course).
(I've tried searching this group, but it seems to fail (groups
broken?), so apologies if this has been reported/covered already.)
