Observed in Firefox 3 Mac.

According to the source code comments for .remove():

// Handle multiple events seperated by a space

// jQuery(...).unbind("mouseover mouseout", fn);

This does not appear to actually work; the second event type supplied does nothing. Steps to reproduce in Firebug:

Environment: any page with a visible element (we'll call it <div id="test"></div>) and jQuery loaded.

$('#test').click(function() { console.log('click'); });

$('#test').dblclick(function() { console.log('dblclick'); });

Now clicks and double-clicks will log the appropriate messages.

$('#test').unbind('click dblclick');

Clicks no longer log messages; double-clicks incorrectly do, though.
