Yeah, I know.  This is not what my program actually does.. I changed the 
return statement to the class name for debugging purposes, and my else 
case is entirely different- I just simplified it so that I would only be 
posting the relevant part of the code, which was the conditional.

Right, that's how I felt when it happened.  But if I remove all calls to 
this method from the program, it does not hang, and like I said earlier, 
if I change the conditional to something like

if ( @thisLine.class == 'NilClass' )

Then the program does not hang, although the code obviously does not 
function as intended.

Thank you for the solution to my problem. @thisLine.nil? worked like a 
charm.  However, I am still bewildered as to why this problem arose in 
the first place... anyone know?
