I've had to use Homebrew on another machine so have been able to reproduce a problem with the Qt formula. As @mxcl pointed out might happen a while ago (but I never got around to fixing) Qt is compiled with SSE 4.2 support which (unsurprisingly) fails to work properly on machines which don't have this capability.

I think we have two possible options:
1) Only build on machines with SSE 4.2 in future and only use the bottle on those machines.
2) Build the bottle to be more generic but therefore slightly slower

In the short-term I think it may be worth removing the Qt 4.8 bottle until I fix this (some time over Christmas).

@adamv @Sharpie @jacknagel @mistydemeo @mxcl: your thoughts?
