terminate called after throwing an instance of 'NSException'

Heres the code i am using in didFinishLoadingWithRequest

-(void)network:(WNetwork*)network didFinishLoadingWithRequest:(NSInteger)pReq data:(NSMutableDictionary*)pData
{
    [self removeLoader];

    switch (pReq) {
        case JBJsonParser:
        {
            NSArray *parsedString = [pData objectForKey:@"placesname"];
            DLog(@"LIST %@",parsedString);
        }
    break;      
        default:
            break;
}

}

in the network class i am using dis code:

{
    SBJSON *parser = [SBJSON new];      
    NSString *dataString = [[NSString alloc] initWithData:mRespData encoding:NSUTF8StringEncoding];


    NSMutableDictionary *newDic = [dataString JSONValue];

    if ([(id)mDelegate respondsToSelector:@selector(network:didFinishLoadingWithRequest:data:)]) {
        [self.mDelegate network:self didFinishLoadingWithRequest:mReqType data:newDic];
    }
    [newDic autorelease];

    [dataString release];
    [parser release];
}
