Here's the text from the above MacFixit article (20070706)
that sums up the problem (and resolution) nicely.


---------Start--------------------------------------------
Crashing (especially Safari)? Remove Input Managers first!

A recent cartoon in The New Yorker shows a doctor telling
his patient: "Sure, it's a routine procedure, if you
routinely have someone slice you open with sharp instruments
and then fiddle with your insides." Pretty funny, eh? Who
would "routinely" permit that? Yet MacFixIt readers do
routinely do something analogous to applications that they
depend on - and then they wonder why those applications
are behaving oddly.

We here at a MacFixIt continue to receive email from people
who are disregarding our advice about Input Managers. How
many times do we have to say it? We've told you in the past
here (for example), and recently here and here. And we have
repeatedly referred to this article, which explains what
Input Managers do. They reach right into an application and
alter its code! This puts the behavior of the affected
application outside the control and responsibility of its
developers.

To permit that kind of thing is to revert to the confusion
of Mac OS 9 and before, with its conflicting INITs and
Extensions that were so difficult to manage and caused all
kinds of incomprehensible crashes. If an application
doesn't have a feature that you want, place a feature
request with the developers, or use a different application.
Don't modify the application behind the developers' back.

At their worst, Input Managers can be a massive and
frightening security hole. Remember, one of these puppies
can make your applications do things they were never intended
to do. That's what the Oompa-Loompa trojan was all about,
remember? The trojan was itself just a proof of concept, and
didn't make your application's misbehave in any drastic way;
but it could have, and that was the point.

Just today we received this email:

  Dear Sirs:

  Safari 2.0.4 freezes on Mac OS X 10.4.10 while surfing
  Internet. Console says:

  2007-07-06 08:07:28.023 Console[1117] *** -[NSBundle load]:
  Errorloading code /Library/InputManagers/Menu Extra Enabler/
  Menu Extra Enabler.bundle/Contents/MacOS/Menu Extra Enabler
  for bundle /Library/InputManagers/Menu Extra Enabler/
  Menu Extra Enabler.bundle, error code 2 (link edit error
  code 0, error number 0 ())

  I am puzzled.

Well, stop being puzzled and try the advice we have given
again and again. Stop using Input Managers. Just stop it!
Locate your InputManagers folders (in your user Library
directory and in the top-level /Library directory), empty
them, and restart the computer. Yes, you'll lose some cute
customization, but you'll gain a computer that operates
with more of the stability and predictability that you
expect from Mac OS X.
