Tried with Chrome 4.0.249, Firefox 3.0.6 and all have the same behaviour:

Always error when trying to view the Word document previously downloaded:
Damaged or corrupted

Sometimes error when trying to view the PDF document previously downloaded:
Damaged or corrupted

Seems to depend on the origin of the content printed to PDF (Word, browser...). Not tested all combinations.

Always error when trying to download / view a JPG image:

SYSTEM WARNING: finfo::finfo() [finfo.finfo]: Failed to load magic database at '/usr/share/misc/magic'.

SYSTEM WARNING: finfo::buffer() [finfo.buffer]: The invalid fileinfo object.
