Embedding JPGs error

[Wes Garrison, Databasically]

I've used prawn for several years now, but this is a new error:

Failure/Error: page_counter =
PDF::Inspector::Page.analyze(doc.render)
PDF::Reader::MalformedPDFError:
PDF malformed, expected 'endstream' but found 0 instead

Same error for any of the analyze() methods.

Outputted PDFs won't open (via OS X Preview).

It happens when I'm embedding JPGs; if I convert them to PNGs they
work ok. I've tried big images, small images, several variations and
can't get anything to work.

I'm tracking prawn master on this project, but the code in image/jpg/
png hasn't changed in a couple months, so it sure seems like someone
else would have run into this before me. I happen to be on c041a7,
specifically.

I don't get the UnsupportedImage exception when adding the file, but
it looks like the file isn't being embedded into the PDF at all.

Suggestions? If I can provide more information, let me know what.

Trying to understand your workflow here. Are you feeding the output of
Prawn into pdf-inspector? Can you give a sample of the PDF that is
causing the pdf-inspector errors?

I'm doing basically the same thing as the prawn tests:

page_counter = PDF::Inspector::Page.analyze(doc.render)

Minimal lines of code to reproduce:

Been kinda stumped about this for the past couple days, so thanks,
Brad.

This works for me with a JPEG I had around, using
data/images/fractal.png from the Prawn distribution. Can you provide
the banner.jpg image that is causing problems?

Your test seems to be working for me, under the latest Prawn master
(c041a778) and Ruby 1.9.3-p0. The resulting PDF opens in OS X Preview
and shows the banner image.

Anything weird about your environment? Are you on a strange version /
patchlevel of Ruby? On Windows or another strange platform?

I don't have any idea what else to check! I'm running in a separate
gemset, but it's apparently something local to my machine.

Guess I... do something else. Maybe I'll try 1.9.3 and see if that
magically resets something. Not sure what else to try, but thanks for
confirming.
