9684	"Type error when nothing is selected in checkSelectionChange() (Cannot call method ""getType"" of null)"	Jeremie Miserez		"Version: 4.x Nightly (Rev. 3952)
The call to a.getType() will fail, as the function getSelection(1) can return null.

{{{
function b() {
                var a = this.getSelection(1);
                if (a.getType() != CKEDITOR.SELECTION_NONE) {
                    this.fire(""selectionCheck"", a);
                    var b = this.elementPath();
                    if (!b.compare(this._.selectionPreviousPath)) {
                        this._.selectionPreviousPath = b;
                        this.fire(""selectionChange"", {selection: a,path: b})
                    }
                }
            }
}}}

The corresponding source code would be in: core/selection.js at line 15
{{{
function checkSelectionChange() {
		// Editor may have no selection at all.
		var sel = this.getSelection( 1 );
		if ( sel.getType() == CKEDITOR.SELECTION_NONE )
			return;

		this.fire( 'selectionCheck', sel );

		var currentPath = this.elementPath();
		if ( !currentPath.compare( this._.selectionPreviousPath ) ) {
			this._.selectionPreviousPath = currentPath;
			this.fire( 'selectionChange', { selection: sel, path: currentPath } );
		}
