I will point out that finding and root causing a bug (and perhaps writing a test) is THE contribution. Very often fixing the bug, once all unknowns have been resolved, is trivial.
Many times a one line fix takes days off debugging and analysis. Seems like this was the case here, since the original bug was open for 6 years.
