Noticed while testing for 3.1.20 Kleopatra no longer shows an error if you enter a wrong passphrase for pkcs#12. It only shows 0 imported. Somehow the error is lost. This is with GnuPG 2.2.33
But the errors from PKCS#12 import were never really nice as kleopatra showed things like "BER Error" and so on instead of a helpful text that the passphrase might have been wrong. So improving this while checking for the missing error would be nice.
