What exactly do you mean by bug here? That construct is the bash syntax to 
specify that if the variable is not defined then use the default value, 
the one that comes after :-
That construct was used exactly to avoid having to test if the variable is 
defined or not before assigning the default value.

dawn:~$ unset A # A is not defined
dawn:~$ A=${A:-ask}
dawn:~$ echo $A # so the default value is used
ask
dawn:~$ A='yes' # A is defined
dawn:~$ A=${A:-ask}
dawn:~$ echo $A # so the default value is ignored
yes
