iphone reboots after switching language

I'm devel开发者_StackOverflow社区oping iphone application with localization in Russian and English languages. For localization I use Localazible.strings file, and also have a copy of Russian and English set of images. The problem is: when I switch language and application is running in background, and then I'm trying to run application, it crashes, iphone reboots, and starts rebooting over and over. Only switching off and then switching on helps. After doing it I can run application in any language. When application crashes debugger says only "program received signal 0". How can I get reasons of such device behavior? These problem occurs on iphone 3gs with iOS 4.1 (jailbreak), iPad with iOS 4.2.1, iPhone 4 iOS 4.3.3 and DON'T occurs on iPhone 4 iOS 4.2.1.

When you change the language while debugging an app through Xcode, the app is killed by the system (during the reboot) and the debugger interprets that as a sigkill, which is what it is telling you - "program received signal 0".

Because the debugger has seen your app killed, it needs to be stopped from within Xcode before you can run it again, other wise you get what looks like a crash on launch and other such errors like "broken pipe" or "unable to start debugger, maybe it is hung in another process".

You won't be able to test a normal "resume from background" when changing language because changing the language restarts springboard and therefore your app is killed.

If you maintain UI state manually (as used to be required before multitasking) then you can restore it on the next launch of your app and maintain an illusion of multitasking.
