At my current job, 2 years, we have a bug that existed before I joined. However, I was able to provide an alternate solution to it. Its hard to quantify the time spent on it because it was always around. When it became a main focus it probably took me 2 weeks to get an alternate solution.

I think this probably happens a lot of the time. Problems exist and existing team members give up on it until someone just says screw it, lets just rewrite that part of the code or someone new comes along and suggests something different.
