PDF-files can have attachments (e.g., added with acrobat professional or pdfLaTeX). It seems a lot of attachment extensions result in acroread blocking the option of saving/opening the attachment. This is due to the security settings in </opt/Acrobat7/Reader/GlobalPrefs/reader_prefs>, where, roughly, 3 means 'Prohibit', 2 means 'Allow' and 1 means 'Allow after dialogue'. See <http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=331371> for more info.
The current settings (lots of 3's) are annoying: it isn't even possible to save attached tar.bz2 files and such. I suggest changing the ebuild such that all 3's in reader_prefs are changed (by some sed script?) to 1's, which is still secure (but puts responsibility with the user) but not annoyingly restrictive.
Steps to Reproduce:
1. open pdf-file with attachment
2. try to open/save
3. observe message claiming opening the file is not allowed
If you find this annoying, then you should file such feedback to Adobe; we are not doing anything with default preferences in the ebuild.

I can understand that. I've filed a bug report with Adobe (no link, not an open system...). I will report back here if (if they reply...) Adobe thinks this is a distribution issue.
Marking UPSTREAM, not a Gentoo issue.
