Whenever I build a custom image in Hob (using Create your own image), I get the following error output once the image build stage is completed:

Traceback (most recent call last):
  File "/home/user/poky/bitbake/lib/bb/ui/crumbs/builder.py", line 1096, in handler_build_succeeded_cb
    self.build_succeeded()
  File "/home/user/poky/bitbake/lib/bb/ui/crumbs/builder.py", line 1029, in build_succeeded
    version = self.recipe_model.get_custom_image_version()
  File "/home/user/poky/bitbake/lib/bb/ui/crumbs/hoblistmodel.py", line 696, in get_custom_image_version
    return self.custom_image_version
AttributeError: 'RecipeListModel' object has no attribute 'custom_image_version'

The UI is the stuck at 99% (do_build). However, the image build process has otherwise succeeded (the image files exist in the images folder). However, Hob needs to be force closed.
