What input do you give it? (When the prompt says
"Search for (something): ", what do you type before
you hit RET?)

If you provide us with more information, we'll try to
reproduce it as well :)

I don't think that is it. `rgrep' has another
interface. The "r" is either "recursive" or, more
likely, "regular expression" or "regexp" as it is
called in the help for rgrep. Which I think is the key
to your problem, because you probably gave it some
strange input which isn't interpreted literally.

Meta: It is a good idea to find some other way to
quote arbitrary material, because that which you just
used will be interpreted as a citation from a previous
poster and by some clients even hidden by default.

I think so: again, what input do you give it? I think
if you tell us that the problem will be instantly
solved :)
