Why does my iPhone Jailbreak Keep crashing?

I installed the iOS 6 Jailbreak and i have been using it for awhile and i try to hold a app down to get them to wiggle so i can move them and or delete them but when ever i hold them down the jailbreak crashes and it puts my device in safe mode i'm not sure why this is happening if it is a certain tweak i have or what please help!
