Bug 65778

Why is this a poppler bug?

The cover says (Google Translate):

"To work with documents in a PDF package is the use of Adobe Reader or Adobe Acrobat version 8 or higher is recommended. The following benefits are available at an update to the latest version available:
[..."

It seems to me this is the PDF equivalent of "<noscript>Your browser does not support JavaScript!</noscript>".  As poppler renders PDF, I think it could be expected to deal with this kind of document.

IIUC, it defines the document as /Subtype application/pdf.  Not having anything else, it might be possible to just show its content.  Please, let me know if I am wrong.

The pdf is attached, you can see okular gives you the attachment, you can save it an open it. Not sure if evince supports showing the attachments. To support what adobe does one could just see if the attachements are pdf files and offer to open them too.

Honestly i don't see what we have to do in poppler.

Evince does the same as okular.  The behaviour expected with packaged pdf is to show the pdf instead of the message (as Acroread does).

Ok, right, the file specifies the "Collection" entry we don't parse, we should parse that and expose it to the viewer.

Patches welcome, should not be very hard :-)

The problem is reproducible with poppler-glib-demo master (>0.22.4)

Inside the PDF, there is an automatically created JavaScript code which has syntax errors (double quotes). You can see it in the JS debugger or in the PDF source code (in any text editor)

PDF test case with inline pdfs

There is a bug in Adobe Acrobat, when the language is set to German: A script code with syntax errors is generated when saving a file with PDF attachments using the 'Reader extended PDF functions' > 'Enable Additional Features'.

The created JavaScript code uses double quotes for text highlighting within the function FileAttachmentsCompatibility.
