Crash in SDWebImageManager imageDownloader:didFinishWithImage:

[chrismcb]

We recently released our app to the appstore, and almost immediately got a few crashes in SDWebImageManager imageDownloader:didFinishWithImage:
The top of the stacks look like:

0 libobjc.A.dylib 0x33c28c98 objc_msgSend + 16
1 CoreFoundation 0x308f0571 -[NSObject(NSObject) performSelector:withObject:withObject:] + 25
2 Ourcode 0x0001d98f -SDWebImageManager imageDownloader:didFinishWithImage:
3 CoreFoundation 0x308f0571 -[NSObject(NSObject) performSelector:withObject:withObject:] + 25
4 Ourcode 0x0001cb03 -SDWebImageDownloader connectionDidFinishLoading:

We have the recent code that does a retain on the delegate inside this function.
As long as our delegate is created properly, I don't see how we get into this situation

[rs]

Please ensure the delegate property is correctly set to nil in the dealloc of the delegated object.
