I just updated the Bookmark Buttons Startpage to version 1.2.2 which fixes a problem that is recognized by the current version of Google Chrome, but not by the previous ones. Also the webstore presentation was updated in order to comply with the new formats.
The extension should update automatically over the next days, but you can manually update it if you go to the extension management window and hit the “Update all extensions” button.
As a sidenote: Chrome 15 does now throw a fatal error when a new RegExp object is created with unrecognized / invalid flags. Turns out that JavaScript does not support the /s flag.
