It might be sufficient to check if the list head is null before trying to
remove the transfer from the list since the transfer is not on a list when it
completes. Try adding the check:
if (itransfer->list->list_head)
on lone 1534 of io.c before:
list_del(&itransfer->list);
And let me know if that resolves the issue.
