On a clean install of OpenAFS 1.6.0pre4 on Mac OS 10.6 
I'm getting the attached message in Console, starting with
 "AFSBackgrounder: HIToolbox: ignoring exception
 'getNewTicketIfNotPresent'..."

To reproduce:
Install our site's /Library/Preferences/edu.mit.Kerberos -- from 
  http://tig.csail.mit.edu/twiki/bin/view/TIG/InstallingKerberosOnMacOSX
Install openafs 1.6.0pre4 for 10.6 on 10.6.7 with all updates
without rebooting, choose settings for System Preferences -> OpenAFS...
...AFS menu, Backgrounder, Use aklog: YES
...Get Krb5 credential at login, get credential at login time: NO

Go to AFSBackgrounder icon -> get new token
...and no dialog box ever appears; it just fails silently while
logging the uncaught exception.

>From Terminal, kinit && aklog works fine.

I've seen this on two MacBook Pros, one Mid 2009 with 32-bit kernel,
the other Early 2011 with 64-bit kernel, over multiple reinstalls
each.

These steps work fine on the computer with 1.4.14.1 (when configured
for 32-bit kernel).  Given the AFSBackgrounder and aklog changes that
hit in 1.6.0pre4 and pre3 according to the release notes, I wanted to
test OpenAFS-1.6.0pre3-2-gff7e8 which I'd been downloading from the
link in
https://lists.openafs.org/pipermail/port-darwin/2011-March/001355.html
but it looks like Derrick has cleaned up his home directory. :-(

As with my email from a few minutes ago, I've got a test laptop that
can be booted into either 32-bit or 64-bit kernel, if that helps.
