A fix for this is modifying this line of code (line 174):

    [self setAutoresizingMask:UIViewAutoresizingFlexibleHeight];

to

    [self setAutoresizingMask:UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight];

and also a bit further down (line 179)

    [self.imageView setAutoresizingMask:UIViewAutoresizingFlexibleHeight];

to

    [self.imageView setAutoresizingMask:UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight];
