Attached is Philippe's test file with object 7 uncompressed. You'll 
notice I've deactivated the line:

   0 0 0 0 0 0 cm

it is the one which gives the "Wrong operand type" message at my end. And 
without it the file renders fine with Linux AR, at least for all the 
versions I have. So the file is malformed in the sense that multiplying 
the current transformation matrix by a null matrix is a bad idea; Philippe 
is this one of your mods? All I can think is that Adobe Pro X/Win 
ingnores the concatenation, ditto for xpdf. When I get the chance I'll
delve into xpdf's source to see what it does.
