Comment(by anonymous):

 Here is a use case that arises from modular multi-component options
 processing: a variables_map is passed to the init functions of components,
 where their options are parsed. Sometimes, I want to set some property
 values after parsing in one component and then the variables_map is passed
 to another component for further processing with its own set options. This
 currently doesn't work due to the notify crash.

 My current workaround is don't call notify ever and missing out 2 nice
 features (setting a variable via typed_value and of course notifier
 itself.)
