Another check of the unzip man page yields the likely reason for your problem. Closing a pipe causes the writer (unzip in this case) to receive SIGPIPE. unzip subsequently returns a non-zero exit status (sets $? to SIGPIPE, or 13), which may be causing croak to fire. You may want to change you logic to not croak if the close fails, but $? is set to 13
