Why does "Chromium Helper EH" crash when I try to launch Chromium? Every time I launch Chromium, a dialog box appears almost immediately telling me that "Chromium Helper EH has unexpectedly quit." Several things don't work, including the New Tab button missing the + symbol, several keyboard shortcuts don't work, and pages don't load more than halfway. What's happening and how can I fix it?

(Extra phrases to help this show up for people searching for "Google Chrome": Google Chrome Helper EH, Google Chrome crashes.)
It turns out that in 10.7.3, installing Chromium/Google Chrome from another account causes this bug. Simply installing it while using the account it will be used in solves the problem. Unfortunately, no other accounts can use it.
