Safari crashes when deleting gadgets from google.com/ig. This is reproducible with r37604. The crash happens everytime I try to delete gadgets. I do not have the software to debug, the crash might be tied to some popup notifiers related to javascript. When deleting gadgets, a popup should appear that asks if you really want to delete the popup. I have experienced similar behavior at secure.almsa.com, a site I use for work, but it requires a secured login so the rest of you would not be able to reproduce it. I cannot reproduce this behavior on r36882, but I can with all nighlies afterward.
Works fine on ToT (r71965)
