When parsing all file information, eventually encounters an invalid block for the file Opening_End_Seq.bik, which is a fairly large file.

This was not broken with the merge of #1254, problem existed prior.
Could be related to #617.

Seems to be fixed with: #2216

It still triggers assertions, however game works.

On master probably crashes only due to broken log in stfs code and should also trigger the same assertions as that PR is mostly about moving code instead of modyfing it.
