This has been happening for a while now and causes a crash at least once a day
with heavy browser usage. It doesn't seem to matter which site it crashes on
and is not directly repeatable. It's more a "the longer you browse, the more
likely for it to eventually crash thing". Since It's so non-specific I don't
know how to describe it further. It's just driving me nuts.

Here's the crash thread information. Let me know if you need more from the
crash logs. I currently have 5 from the last 5 days, but the crash thread is
the same in each.

Exception Type:  EXC_BAD_ACCESS (SIGBUS)
