It's die'ing because of an uncaught exception so, erm, perhaps catch it?

Update: Additionally, perhaps check the frelling status of your get before blithely and unconditionally proceeding on as if everything were hunky-dory?

If you've got a site that intermittently has hiccups something like this get wrapper might be useful:

use constant MAX_FETCH_ATTEMPTS => 5;
use constant RETRY_FETCH_DELAY  => 2;

sub _get_with_retry {
    my ( $m, $url ) = @_;

    my $tries = 0;

    my $result;
    until ( $tries == MAX_FETCH_ATTEMPTS() ) {
        $result = $m->get($url);
        last if $result->is_success;

        $tries++;
        sleep( RETRY_FETCH_DELAY() );
    }

    return $result;
}

Update the second: Of course _get_with_retry would be kinda useless with autocheck enabled. Then again since you didn't bother to wrap your code in the correct tags I missed that it was set.
