UICollectionView mysterious crash

Question

I have a UICollectionView where I am filling up the cells with images downloaded from the Internet. For this I am using SDWebImage. My code looks like this:

-(UICollectionViewCell*) collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{

    NSString *CellIdentifier = @"Gallery_Cell";

    GalleryCell *cell= (GalleryCell *)[self.flowCollection dequeueReusableCellWithReuseIdentifier:CellIdentifier forIndexPath:indexPath];

    if (indexPath.row < self.collectionData.count) {

        CellDetails *dets = [self.collectionData objectAtIndex:indexPath.row];

        NSURL *mainImageURL = [NSURL URLWithString:dets.imageURL];

        cell.image.contentMode = UIViewContentModeScaleAspectFill;
        cell.image.clipsToBounds = YES;

        [cell.image setImageWithURL:mainImageURL placeholderImage:nil];
    }

    return cell;
}

I believe I have set this up correctly. But the app crashes (EXC_BAD_ACCESS) completely at random sometimes leaving this stack trace:

There is no other message in the log area. I tried setting an exception breakpoint, but each time this crash occurs, showing this stack trace. Does anyone have any idea what might be the problem?
