I've had this issue with Chrome and Chromium for some time, thinking it was due to the fact that iconset I'm using is missing some Icons , but I've tried with many different sets and apparently none have the the correct Icon.
Is it Chrome/Chromium that is expecting another icon? (and what would it's name be?) or the sets i have just don't have that Icon?.

I had the same issue.
Solved it by installing the "gnome-icon-theme-full" package.
