there was a seahorse-daemon process that went berzerk with this crash (using at least 74% of my CPU time) which goes on with every crash and I have to kill manully

this is what I have found on my /var/log/auth.log

and this is what the bzr vis echoed as stdout on the shell I was running during the crash:
