1. Go to http://docs.google.com and sign in
2. Create a new document and add some text content
3. Click on Insert > Picture
4. Select an non-image file (did this accidentally)
Error popped out that image is invalid then the browser crashed.
I cannot confirm the problem. I've got error message but WebKit r35289 didn't crashed.
Tried on WebKit r35130, and works fine now.
