This line simply raises a TypeError that's unrelated to the
business-logic-level problem. Make it more user-friendly?
I know I wrote that line, but I meant it as a placeholder. (Compare
r1869139.)

Aside: the colon here isn't redundant, as it would be if «line» were
a str:
>>> type(b'foo'[-1])
<class 'int'>
>>> type(b'foo'[-1:])
<class 'bytes'>
>>> type('foo'[-1])
<class 'str'>
>>> type('foo'[-1:])
<class 'str'>
Cheers,
