i think this one is a trivial crash- one i fixed a long while ago-

but there are lots and lots of other things lurking- potentially-

noone should be updating a working machine to lion- there is no reason to- there are no new features that are off any use to anyone - except a whole heap of broken and removed stuff -

even basic stuff on apples side is quite broken-

i mean they broke keynote- their own application-
i tried to use it recently- just sat their spinning beach balls.
half-baked auto save functionality that simply does not work with large files
its a big design flaw with something like keynote
4GB file with embedded movies - now a flat file instead of a bundle

they broke or changed lots of stuff that simply did not need to be broken
