GMail complaining about Konqueror

When I login to Gmail via Konqueror, I get the following "advise": For a better Gmail experience, use a fully supported browser. When I click the "click here to learn more" I learn that Gmail has put me in simple HTML mode "which should be readable on almost any browser" but that some of the more fancy functionality would not be available. And it's true: it doesn't autocomplete previously used to/cc addresses, the "move to trash" combo box doesn't automatically work and I have to click a "go" button next to it to have my option executed, and so on. Do I file a bug with KDE or with Gmail? Anybody else has this experience?
