Chrome Kerberos auth breaks with MacOS 10.7.4 patch?

I have installed the new 10.7.4 update on my MacBook and promptly the Kerberos Auth of our Trac and FreePBX broke down in Chrome. I have not a clue why this is so, but it seems to affect only Mobile (account) users...

Puh... work, work.

- update -

It's still possible to give Chrome the Whitelist parameter manually:
open /Applications/Google\ Chrome.app --args --auth-server-whitelist="*.example.com"


- update 2 -

I've found the source file with all cmdline switches for chrome/chromium. Took me long enough to find, so I'm documenting it here:
