--- Comment #7 from Jaime Torres <jtam...@gmail.com> ---
I'm able to reproduce it with one of the dni readers and the pkcs#11 dnie
library installed:
Just connect any dnie reader to any usb, with or without any dni, and open any
pdf with signatures, for example:
/usr/bin/okular
"https://www.tecxoft.com/samples/pdf_digital_signature_timestamp.pdf";
In Valgrind:
