file\_column does not handle inconsistency between the database and  
filesystem well.

If I define an url\_for\_image\_column like this:

url\_for\_image\_column(  
@ad.images.first,  
“image”,  
{  
:geometry =\> “120x90”,  
}  
)

It returns a wellformed url for the resized image.

BUT if I accidentally delete the image-file from the filesystem (in the  
folder public/image/etc…), the above code results in a a NoMethodError

NoMethodError in User#welcome  
Showing app/views/shared/\_ad\_list\_frame\_dog\_sell.rhtml where line #60  
raised:

You have a nil object when you didn’t expect it!  
You might have expected an instance of Array.  
The error occurred while evaluating nil.split

What is the problem?
