Do any of those touch the lockscreen? For instance do you have Springtomize theming anything, or a theme running in Winterboard, etc? Maybe try disabling Zeppelin to see if that helps with Chip.
Ideally, you could install Crash Reporter from Cydia, and the next time you crash you'll have a log of what went wrong to help pinpoint the problem. Otherwise it's often just trial and error, trying to find the conflict. One thing I have been reading though is that with Chip a respring will trigger Safe Mode but a reboot will work fine. Worth a shot. I know the developer was working on a Safe Mode loop issue a couple of weeks ago--do you have the latest version? And legit, right?
