Olivier, I also suffer from this bug several times a day especially when I am using IRCCloud but tonight I opened the Ubuntu Wiki in a third tab and the CPU usage for gnome-keyring-daemon immediately rose to around 62% and stayed there for over a minute.
I'm attaching a log as you requested above which I let run until the CPU usage fell back to an acceptable level.
I'm using Ubuntu 18.04 and Chromium 68.0.3440.106.
