Well, it's noon. I'm at my office with my workstation doing strenuous amounts of work. Chrome has about 15 tabs open. And I find a new way to crash it. Couldn't find it on the net yet, so I'm duty bound to post it, sorry Google :(
Here's how you can repeat it too:
Open a web page in chrome and open History. This will be opened in a new tab.
Pick a day on which you have visited large number of pages. Click "Delete history for this day". Say OK at the popup and immediately close the History tab..
Thats right. Yeah go on, give it a try..
EDIT: This seems to be a one off incidence. Me and Chrome having a bad day. It never misbehaved with me in this fashion ever again..
