When I go to line no. 140 in DistanceViewController.m (crashing point, as suggested by log), i find:

cell.backgroundImage.image = barImage;

Where "barImage" is a UIImage defined in this class and initialized in initWithNibName method as:

barImage = [UIImage imageNamed:@"Bar.png"]; 

I do not release barImage as I have not alloc/retain it anywhere. Also, distanceViewController's initWithNibName is only called once in the app.

Can anybody point me to where I should be focusing on to get rid of the crash here?

As noted in App crashes after launching on OS 3.1 perhaps if you used the same OS in development as your client is running themn you would find the crashes before you released the code.

You at least would have the correct symbols to give some idea and be able to run in the debugger
