After playing around with more parameters that could isolate or remedy the problem, I found out that, by coincidence, aqbanking-tools stopped working with my bank the same time that this gnome-keyring bug occurred.
So at least for aqbanking-tools, gnome-keyring doesn't break it. Regards Marc-Jano -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
