When I start Chrome, I sometimes get a little ! (exclamation mark) on the tools popup menu. When I open the menu, there is a new entry "Extensions Error". When I select it, it goes to chrome://chrome/extensions/ but on that page, there is no indication which extension has/causes problems.

How can I find out what is wrong?

On top of the extensions page chrome://chrome/extensions/, there is a checkbox "developer mode". Select it and an explanation of the problem should appear in a red box next to the extension which causes the problem.
