Hi,

Hum, initially I was inclined to close this bug as a transient error
from network.  However,

    > substitution of /gnu/store/mzfkrxd4w8vqrmyrx169wj8wyw7r8i37-bash failed

should not raise this ugly backtrace.  Well, I do not know if it is a
bug or a wishlist. ;-)  It could be nice to handle that.

Cheers,

PS: Since the tracker has already some concrete bug, I am also fine to
    close this wishlist. :-)
