[cups.bugs] No print of PDF file from AR

[alupu at verizon.net]

I sent the message below to "cups-bugs" a couple of days ago and no response yet.
Am I missing the proper way to submit a bug (a la "Bugzilla")?
Please let me know what I should do to get the attention of a specialist.
Thank you

NOTES:
1. The "problem" file is a 2-page 66924-byte standard rebate text from newegg.
   It's possible the file is imperfect PDF but
2. It prints without problems from AdobeReader (7.0.5) on Win XP (SP2)
   (same physical system - dual boot).
3. Same problem with AdobeReader 7.0 and 7.0.8
4. The file is _displayed_ perfectly in AdobeReader, gs and gsview.
5. CUPS prints perfectly any other file from AdobeReader, and any kind of
   file from any other application (including command line).

Thanks,
