Lyx 2.4.Dev Crashed after copying a section

[Wolfgang Engelmann]

Using lyx 2.4.dev
it crashed after copying a section in a book document (A) from another 
version of the book (B). The book A contained already identical labels 
and the crashed occurred after quite a number of them was shown in the 
terminal (shown only a few here)
