Steps to reproduce the problem

I get a runtime error for certain documents during rendering: kidDict.getRaw is not a function. However, the document renders and works "just fine" for my needs.

I have tried to debug the error a bit and it happens on this line, because the line above kidDict = this.dict.xref.fetch(kid) returns a number, 1 in my case, and not a Dict object. I haven't followed the code enough to know what the number means, but it's certainly not the Dict object we expect in the code path.

What is the expected behavior?

Not to issue a runtime error.

What went wrong?

Nothing, as far as I can see. There may be broken functionality we don't use, I dunno.
