-----------------------------------------------------------------
The /Size entry of the XRef stream is very suspicious:
{code}
<<
/ID [<D1937B3FD680CC64D5EBCC37CBBFA250> <9C81007F4396CCA0A2C2DFBD3E3C5F31>]
/Info 144 0 R
/Root 146 0 R
/Prev 116
/Type /XRef
/Size 4
/Index [0 1 146 1 244 2]
/W [1 3 0]
/Filter /FlateDecode
/Length 24
>>
{code}
/Size should be 247, not 4: "The number one greater than the highest object
number used in this section or in any section for which this shall be an
update. It shall be equivalent to the Size entry in a trailer dictionary."
Changing the /Size entry manually allows the file to be shown in Adobe Reader
(of course signature is no longer valid).
