Also check maybeLength when deciding if a stream is empty in Parser_makeFilter (issue 6360, bug 1191694)
#6372
Conversation
…r_makeFilter` (issue 6360) The problem with the PDF files in the issue, besides the obviously broken XRef tables which we're able to recover from, is that many/most of the streams have Dictionaries where the `Length` entry is set to `0`. This causes us to return `NullStream`, instead of the appropriate one in `Parser_makeFilter`. Fixes 6360.
