Confirmed, in current SVN too.  You don't even have to move a line in my case, just pasting crashes it.  Pretty bad, this one.  It does seem to be not just the beziers, though -- trying the same trick with render_test.dia but having removed all bezier-related items.  You don't even have to close the first diagram, as long as the copy goes into a different diagram.

Thanks for the nice test file, fix just commited:

2008-04-08  Hans Breuer  <hans@breuer.org>

	* lib/object.c(object_copy_list) : if we can't find the object to
	to connect to ensure there is no dangling reference. Fixes bug #497070
	* lib/group.c(group_copy) : some comment
