unable to list source for <exception thrown> should never occur
I get the very unhelpful "unable to list source for <exception thrown>". I would like to get one of the following two responses, the last one is best.
Do this and that to list source
We currently cannot list source, because you did and that Do you still want to list source although it requires to do that and that(for example automatically recompiling and reexecuting it until the same program point) [Y/n]?
