Prio high, because it is a reproducible crash. And crashes should always get higher prio.
To reproduce this it is very simple.
- export GNUPGHOME=$(mktemp -d)
- Run kleopatra and gererate a key
- Select revoke certification.
It is already viewable that the keyselectioncombo at the top is empty. If you still confirm you get a crash:
gpg_revsig (flags=0, userid=0x7fffc4002640 "Andre Heinecke <firstname.lastname@example.org>", signing_key=0x0, key=<optimized out>, engine=0x7fffc40023a0) at ../../../src/gpgme/src/engine-gpg.c:3308 3308 err = add_arg (gpg, signing_key->fpr);
