Well, it is easier for us to deal with erroneously submitted bug than
erroneously unsubmitted ones. We have an Add-Ons category on r-bugs to
put it in.
Lattice is closely associated with the core team, so we'd be able to
track this kind of problem. With some other packages which we do not
maintain, we have some trouble figuring out whether a report has been
solved or whether it was even a bug in the first place (it would be
nice if the original submitters would lend a hand there).
As I remember it, Paul and Deepayan were somewhat vague about exactly
what was required, except that you'd need something relatively recent.
A segfault certainly looks like a real bug.
