whats the name of the fix?The tweak probably needs to be updated for iOS 6.x; there are quite a number of internal changes, after all.
I updated the guide with links for evasi0n 1.1. It contains the fix for the Weather app crashing, and squashes a few other bugs. If you already jailbroke with evasi0n, you can get the fix in the form of an update in Cydia.
mine still crashes
