I can get large type in addressbook, but the widget is still broken.
Looks like it's a problem with a nib file (whatever that is...)
Console output gives:
20/10/2009 09:47:41 com.apple.Dock.agent[186] objc[393]: Class ABLargeTypeController is implemented in both /System/Library/Frameworks/AddressBook.framework/Versions/A/AddressBook and /Library/Widgets/Address Book.wdgt/AddressBook.widgetplugin/Contents/MacOS/AddressBook. One of the two will be used. Which one is undefined.
