Hello everybody,

did you experienced an app crash on startup if you build the app for iDevice for the first time?

I cannot find the problem. The backtrace command ("bt all") tells me, it is the [LinphoneManager getLc] method. But I can't see the problem in this lines of code. 

That's the backtrace:

    frame #1: 0x0000bde8 UCware Mobile Pro`+[LinphoneManager getLc](self=0x004290b0, _cmd=0x003ab846) + 168 at LinphoneManager.m:343
    frame #2: 0x000032d2 UCware Mobile Pro`-[LinphoneAppDelegate handleGSMCallInteration:](self=0x0078b1b0, _cmd=0x003ab93a, cCenter=0x0078a970) + 150 at LinphoneAppDelegate.m:63
    frame #3: 0x00003966 UCware Mobile Pro`-[LinphoneAppDelegate applicationDidBecomeActive:](self=0x0078b1b0, _cmd=0x33489300, application=0x0124b6e0) + 770 at LinphoneAppDelegate.m:138

>From backtrace mentioned, these are the lines of code:


line 137  // check call state at startup
line 138  [self handleGSMCallInteration:callCenter];


line 62   NSLog(@"No GSM call -> enabling SIP calls");
line 63   linphone_core_set_max_calls([LinphoneManager getLc], 3);

and in getLc:

line 343  @throw([NSException exceptionWithName:@"LinphoneCoreException" reason:@"Linphone core not initialized yet" userInfo:nil]);

Maybe you experienced the same problem. If you got any idea where I have to look for, please tell me.

Thank you in advance!

With kind regards,
