Deleting list gives back 400 error

The following error is returned:

$ ./tasky.py -d --tasklist 0 -s
This will delete the list "To-Dos" and all its contents permanently. Are you sure? (y/n): y

Trying to delete this via Gmail gives the error: "Your default list cannot be deleted." Maybe Tasky should handle this?
