when compiling input/regression/midi/key-initial.ly

Looking through the code, it appears as follows to me:
-) Grob::internal_set_property calls Grob::is_live (), which crashed in  
line 312 with the check
      return scm_is_pair (immutable_property_alist_);
-) So, it seems like the immutable_property_alist_ member is not  
initialized.
-) All Grob constructors initialize that member from the passed argument  
(either Grob* or SCM props)
-) So, my conclusion for now is that somewhere a grob (or some child class  
instance) is created with the Grob (SCM props) constructor, where the  
passed argument SCM props is some uninitialized value.
