The signing depends upon the rest of the bundle, too, including bundle  
resources.  I wonder if a lipo operation on, say, libpurple.framework  
invalidates the signature for the bundle. The problem might not be the  
removal of the universal nature from Adium.app/Contents/MacOS/Adium  
itself but rather from the operation being performed on our auxiliary  
apps (AdiumApplescriptRunner) and on the frameworks.
