What do I need to do?

Answer 1

I have the seem problem with my iPhone 4s iOS 5.0.1 The emergency method is download a app names respringIcon in Cydia, and when you want debug,open the app choose Safe Mode. App can debug in Safe Mode. -----------update------------- I had update to iOS 5.1.1 with jailbreak,and when I install one software from Cydia I use xCode to debug on phone, but no one make debug not work. I think iOS5 jailbreak had solve this issue!

Answer 2

I had the exact same issue, it turned out TruPrint (which it seems you have installed) was causing problems with the XCode debugger. Try uninstalling it, rebooting the device and then try launching from XCode, it should work.

Answer 3

This page http://www.alexwhittemore.com/?p=398 seems to have the same problem you're describing, and the answer (from that page) appears to be to set up an 'Override' in your Backgrounder.

I have no idea what that means - but it's what the page describes in order to work around the problem.

As always, the only way to "fix" this, is to not use a jailbroken device.
