Hi, This is a known issue, caused by an incompatibility between Chrome/Chromium 10 and the GNOME keyring, as documented here [1]. Workarounds are also noted on that page.
(If you aren't using the GNOME keyring to store your passwords in Chromium, then this would probably be a completely different issue; in that case, please disregard this message.) Regards, - Vincent [1] http://www.google.com/support/chrome/bin/answer.py?hl=en&answer=1230517
