-----------------------------------------
I get an error in Adobe Reader when trying to display the original file, and
the signed file. I did not click on the yellow bar because I'm cautious.
The file has incorrect content in the content stream, e.g. this: "0 0 -29 0 -39
-23 -39 -39 -228 -228 -228 113 -169 158 -76 -16 158 39 143 66 60 40 -7 20 0 0
