Are you sure it has something to do with
webkitWebViewRegisterForIconNotification? I'm thinking what's being
reported in hs_err is wrong because my core dumps show a different call
stack (see previous comment).

It greatly varies. It didn't crash for a few days but I crashed 3 times
the same day, I'm at 6 this week.
