I understand that is what they meant, but it is not what they wrote. They should have qualified the statement as you did, with the conditions that yield a runtime error. Even if they generalized those conditions that would have been fine.

for example:

  or tries to access a library that it is unable to for some reason without handling the resulting error.

Ah, but the existence of a suitable library in the environment is assumed. So not having it is an unexpected condition.

So… most likely it is a “typo” or edit-mistake or similar. If you understand what they meant then all is good, no?
