> In CDVFileTransfer.m, download() method between line 447 to 462
> {noformat}
>     delegate.connection = [[NSURLConnection alloc] initWithRequest:req delegate:delegate startImmediately:NO];
>     if (self.queue == nil) {
>         self.queue = [[NSOperationQueue alloc] init];
>     }
>     [delegate.connection setDelegateQueue:self.queue];
>     @synchronized (activeTransfers) {
>         activeTransfers[delegate.objectId] = delegate;
>     }
>     // Downloads can take time
>     // sending this to a new thread calling the download_async method
>     dispatch_async(
>                    dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, (unsigned long)NULL),
>                    ^(void) { [delegate.connection start];}
>                    );
> {noformat}
> If I replaced it with the older version of the code, then it works.
> {noformat}
>     delegate.connection = [NSURLConnection connectionWithRequest:req delegate:delegate];
>     if (activeTransfers == nil) {
>         activeTransfers = [[NSMutableDictionary alloc] init];
>     }
>     [activeTransfers setObject:delegate forKey:delegate.objectId];
> {noformat}
> In summary, if we don't use GCD to start the NSURLConnection, it works.
