I’m having a strange issue with an iOS app of mine. When it is run via Xcode (Build & Run), all works well. The app launches and everything works as expected.
However, if I try to open the app by tapping its icon as the user would (via Springboard), the app crashes immediately with the crashlog below. It seems to point to some kind of an image-releated issue, but I don’t understand how it doesn’t occur when debugging using Xcode.
Can anyone shed some light?

Edit: Talked this through with the Apple Developer Team. The issue is that I used a self-made plugin in my app that wasn’t codesigned (even though I told Xcode to do so). However, Xcode 4.3.3 has a bug that breaks codesigning for bundles, so we’ll see how this works out soon.
Your application may be taking too long to launch. It is given unlimited time when launching from Xcode, but is not afforded this luxury when launching from SpringBoard.
Take a look at this for reference: https://developer.apple.com/library/ios/#qa/qa2009/qa1592.html
