Are you able to reproduce on a Nightly build?

Yep.  Reproduces with latest nightly.

Comment 3

[Julian Seward [:jseward]]

At Mike Hommey's suggestion, I did Settings -> Privacy -> Factory Data Reset on
the phone, then reinstalled nightly, but it still NPEs.

[Doug Turner (:dougt)]

julian,

Can you add some logging around where mBrowserToolbar is touched?  Why is it null?

Comment 5

[Julian Seward [:jseward]]

I'm sorry, but I don't have a test case any more.  I upgraded the
phone to ICS and nightlies work just fine on that.  I'd be inclined
to close this as invalid, unless someone else sees the same failure
on 2.3.x.
