Can you share the document? Can you reproduce the crash every time? Can you run valgrind okular in a terminal, make what you do to make it crash and attach the output of valgrind here? I can consistently (every time) reproduce this bug in my openSUSE Leap 15.2 system. Just: 1. open signed PDF 2. close it 3. crash I can reproduce even with another PDF document e.g. https://www.tecxoft.com/samples/pdf_digital_signature_timestamp.pdf Created attachment 130062 [details]
valgrind okular
I can't reproduce. So the crash is ==7021== at 0x32B35750: boost::shared_ptr<cryptotech::cpp::utils::ILogOutput>::shared_ptr(boost::shared_ptr<cryptotech::cpp::utils::ILogOutput> const&) (in /usr/lib/ccs/libccpkip11.so.2.00.00261) ==7021== by 0x32B96600: C_CloseAllSessions (in /usr/lib/ccs/libccpkip11.so.2.00.00261) ==7021== by 0x2F08B147: PK11_DestroySlot (pk11slot.c:444) ==7021== by 0x2F08F3D2: SECMOD_DestroyModule (pk11util.c:922) ==7021== by 0x2F08F739: SECMOD_DestroyModuleListElement (pk11util.c:968) ==7021== by 0x2F08FBF4: SECMOD_DestroyModuleList (pk11util.c:983) ==7021== by 0x2F08FC78: SECMOD_Shutdown (pk11util.c:67) ==7021== by 0x2F048D21: nss_Shutdown (nssinit.c:1163) ==7021== by 0x2F048E1C: NSS_Shutdown (nssinit.c:1221) ==7021== by 0x2E6591C8: shutdownNss() (SignatureHandler.cc:31) shutdownNss being poppler saying "i'm done using nss", so it would seem to me either the crash is in nss, in pk11 or more probably in libccpkip11, which is something my system doesn't have. Looking around the internet i think libccpkip11 is the driver for "proprietary PKCS #11 driver for CryptoTech smart cards by CryptoTech". My first suggestion would figure out if you can just uninstall that from your system, it's non Free code that's crashing, not much that we the Free people can do to help you. If you didn't install that on purpose, i'd also suggest you file a bug against opensuse and figure out why they are installing non free code by default. I'm going to close it as NOT A BUG since everything is pointing away from us. If you can remove that libccpkip11.so from your system and okular still crashes please reopen this bug. *** Bug 456910 has been marked as a duplicate of this bug. *** I can not reproduce bug after uninstalling ccs (CryptoTech proprietary driver). 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: ==30095== Invalid read of size 4 ==30095== at 0x662CCC7: pthread_mutex_trylock@@GLIBC_2.34 (pthread_mutex_trylock.c:33) ==30095== by 0x21834709: NativeLockMutex(void*) (in /usr/lib64/libpkcs11-dnie.so) ==30095== by 0x21828C21: C_CloseAllSessions (in /usr/lib64/libpkcs11-dnie.so) ==30095== by 0x1569303E: UnknownInlinedFun (pk11slot.c:452) ==30095== by 0x1569303E: PK11_FreeSlot (pk11slot.c:489) ==30095== by 0x15695F0B: UnknownInlinedFun (pk11util.c:923) ==30095== by 0x15695F0B: SECMOD_DestroyModule (pk11util.c:885) ==30095== by 0x1565E1CC: UnknownInlinedFun (pk11util.c:969) ==30095== by 0x1565E1CC: UnknownInlinedFun (pk11util.c:984) ==30095== by 0x1565E1CC: UnknownInlinedFun (pk11util.c:68) ==30095== by 0x1565E1CC: nss_Shutdown (nssinit.c:1163) ==30095== by 0x1565EEAF: UnknownInlinedFun (nssinit.c:1221) ==30095== by 0x1565EEAF: NSS_Shutdown (nssinit.c:1200) ==30095== by 0x20F933F8: ???
