[BUG] Calendar and [ quote ] tag -> crash

An small but potentially disturbing problem I noticed...
If you post an event in the calendar, and add some [ quote ] tag in it, when you pass the mouse over that event in the calendar, without clicking anything, it will open a new page with only
à ¢Ã¢â€š ¬Ã‚ ¹ Select à ¢Ã¢â€š ¬Ã‚ ºÃƒ ¢Ã¢â€š ¬Ã‚ ¹ Expand à ¢Ã¢â€š ¬Ã‚ º
on it, and this page will keep charging forever...
This issue is only with que [ quote ] tag, if you use a [ b ] tag for example, there will be no problem...
