[Conkeror] Breaking changes in 1.9.1

[Ramkumar R]

Hi,

I just built myself a fresh Xulrunner from the hg tree release 1.9.1
HEAD today and found out that Conkeror is dumping lots of warnings to
my terminal. nicktastic on #conkeror@ irc.freenode.net was testing it
on older nightlies and figured that:
1. Some breaking changes have been made after his nightly.
2. My build is broken.

In order to eliminate choice 2, I downloaded a recent (Jul 20) nightly
from http://ftp.mozilla.org/pub/mozilla.org/xulrunner/nightly/latest-mozilla-1.9.1/xulrunner-1.9.1pre.en-US.linux-i686.tar.bz2
and tried it out. Same result. Some portions of the error log is
attached with this email. Right now, nicktastic and I are trying to
find the last known "good" commit after which the breaking changes
were made in order to bisect and find the code that changed. This may
very well be a false alarm, and we can only know for sure when we find
the bad commit.

Although the output is troubling, Conkeror "mostly works" with this
build. I'm unable to exactly point out what is qualitatively wrong
accurately, except for the fact that the minibuffer doesn't look like
an input box anymore while accepting input.
