Hello Jeff,

Thank you for reporting and sorry for the late response.

Computing of a response curve for two (or more) *identic* images with identic 
exposure times can not work, because the algorithm needs data of at least
two different exposure times. That the plugin crashes here, is nevertheless a 
bug, caused by the curve displayer, where an "asser()" check was left for the 
case of a zero plot range.  The curve you would have seen, was a horizontal 
zero line.

I tried to fix it in the CVS repository, but my developer account seems to be  
removed (Robin?).
