Hi. I happen to also be affected by this bug and managed to narrow it down.
I guess the problem lies in the function sync_initial_tokens_from_driver (https://gitlab.gnome.org/GNOME/gnome-settings-daemon/-/blob/master/plugins/smartcard/gsd-smartcard-manager.c#L461). The code assumes that gck_slot_get_token_info won't return NULL. However looking in gck, it does return NULL if C_GetTokenInfo returns an error (https://gitlab.gnome.org/GNOME/gcr/-/blob/master/gck/gck- slot.c#L688). And this is precisely the behavior of opensc-pkcs11.so when it sees an unrecognized token. It returns the token in C_GetSlotList (as present), but returns an error when calling C_GetTokenInfo. So if you login as a user with your USB token plugged in, gsd-smartcard will crash in a loop. ** Changed in: gnome-settings-daemon (Ubuntu) Status: Expired => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/2016914 Title: gsd-smartcard: segfault on startup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/2016914/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
