Actually, messing with anything in /System/Library has the potential to cause problems.
I've been making the System Folder "better" ever since OS 8.5. Can't help myself. The Helveticas are back, but I still can't run the combo updater, even one I downloaded today. The security update runs okay.
I've successfully fought a strong urge to clean up /System/Library for years, but every time I fire up GrandPerspective I've got to do battle with it again.
Have you tried booting into safe mode to run the Combo?
