This is just mince. There are no long-standing crashes in Safari that "crash the browser with CSS or file selection". And from a purely anecdotal point of view, I've found it the least annoying browser to use by far.
I think you missed the Mobile part. Do a search for "Mobile Safari file selection crash" – that one minor but severe example was still happening as of earlier this year and for at least four years prior. Mmm, mince!
