Looks like this function croaked (see below for traceback):

package RHN::DB::Package;

...

# given varying data, try to figure what freakin' package to load.
# NOTE:  Might I say, this sucketh much donkey wong.  Awaiting a better # answer :(
sub guestimate_package_id {

....

  } else {
    croak "not enough information to make a guess about what package you're
looking for!";
  }
}

is this expected during normal operation?  What could you do in the UI to cause
this error?
