StructRNA of type DP_OT_draw_operator has been removed - when swiching to a new scene

Hi, After opening blender client, I install the widget and invoke it with Ctrl + Shift + k. Everything works fine, the widget displays and works. Then with the widget displayed I click New -> General -> Don't save. In the Console I get the following stack trace:

Then, in the new scene, when I press Ctrl + Shift + k, the widget displays, but in the consol window I get a continuous stream of errors exactly like above. Any idea how to fix this?
