How do you verify that none of your other data gets corrupted? :)
Though I guess there just is a bug somewhere in Apple’s code.
Presumably something like a font cache is accessed by multiple
processes, and so, it could very likely be a race condition (two
processes both adding to the cache).
I did notice that one of the Leopard seeds actually caused sub-daily
font corruption in TextMate’s HTML output window. Relaunching TextMate
fixed it though.
But also since Leopard GM I personally have not had to reset my font
