Comment 1 Oliver Sander 2023-04-27 12:21:36 UTC

Can you try this with a very new poppler and Okular?  The signature code is being worked on and your problem may have been fixed already.

Also, does this happen with every document with a signature?

Can you share such a document?

Comment 2 Albert Astals Cid 2023-04-27 21:58:24 UTC

This is just the typical NSS_Shutdown at exit isn't a great idea and needs to be fixed. We have several bugs about it.
