Intro: If you didn't read the comment I added to my last article about 10.5.8, please do. The script problem I described is isolated to only the Intel Combo updater for 10.5.8. So far I have found no reports of problems using the normal Software Update updater for Intel Macs.
This one has also been verified. It is apparently restricted to the Intel version of the Safari 4.0.3 updater for Tiger.
After installing Safari 4.0.3, you run it and find Safari locks up while loading a web page. The lockup consists of going into permanent sit-and-spin mode via the twirling lollipop of doom.
Restart your Mac AGAIN. Problem gone. QED.
This is the second time in a week Apple have distributed an update with a faulty script. I think someone over there needs a vacation.
I'll discuss the security content of the update over at Mac-Security.
