M13ProgressViewImage crash

[jaumevn]

Hi there,

I'm using this class to indicate download progress. Sometimes I get a crash when is rendering the current progress in createImageForCurrentProgress method. I'm instantiating it with the following code:

self.progressImage = [[M13ProgressViewImage alloc] initWithFrame:CGRectMake(10, 10, 45, 45)];
            self.progressImage.progressImage = [[SDImageCache sharedImageCache] imageFromDiskCacheForKey:self.stickerURL];
            self.progressImage.progressDirection = M13ProgressViewImageProgressDirectionBottomToTop;
            self.progressImage.drawGreyscaleBackground = NO;

Could you post the stack for the crash. That will give me a better idea of what is going on.
