Taskbar Tweaker crashes Desktop Manager with Google Talk

Using Taskbar Tweaker 4.1.1 and Google Talk 1.0.0.104, when Google Talk pops up a notification for a new GMail or Google Talk, Desktop Manager crashes with "Desktop Manager has stopped working". If Taskbar Tweaker isn't running I don't see this message.
