jQuery UI 1.8 uncompressed version
jquery.ui.dialog.js

Problem:
line 174(dialog destroy), 204(dialog close)

self.overlay.destroy();

line 724(overlay destroy)

this.oldInstances.push(this.instances.splice($.inArray($el, this.instances), 1)[0]);

"duplicate overlay.destroy()" makes "instances & oldInstances in $.ui.dialog.overlay" broken.

Workaround-A: line 724(overlay destroy)

var index = $.inArray($el, this.instances);
if (index >= 0) this.oldInstances.push(this.instances.splice(index, 1)[0]);

Workaround-B: line 204(dialog close)

self.overlay.destroy(); self.overlay = null;

I can duplicate this in 1.8.2. Very frustrating. Thanks for the workaround!

Using the latest jQuery UI (1.8.13) this bug appears to be fixed. See ​http://jsbin.com/otama/38 (Updated the original example to use the latest jQuery UI)
