2.Try to open "Signed.pdf" in LibreOffice Draw
3.

Actual Results:
General Input/Output Error

Additional Info:
Acrobat Reader, Atril, Evince, Okular, Sumatra PDF, PDF-XChange, and GIMP have no problem opening GPG-signed PDF files. 
Xournal, Inkscape, and LibreOffice Draw do.

Please attach a sample file, reduced as much as possible, without private information.
