Wait, Chrome updates erase your stored passwords!!?
At least for me they don't. I have 2 passwords stored in Chrome (not a site important enough to go into KeePass), and have been through multiple updates and yet to lose any passwords.
Ah that explains it then. I'm currently on Windows, but used Linux for more than a decade previously and password storage in Chrome was consistently problematic. The coordination with gnome-keyring-daemon always seemed flaky... sadly doesn't look like Chrome are in a hurry to improve this area.
