Sometimes problems with the current version don’t indicate real problems. Obviously a bug is something “broken” but what’s broke to one person isn’t necessarily a problem to someone else. What it really indicates is where people are spending their time. Bugs that exist in areas of the application that no one uses are still bugs but when they aren’t found for months on end it also indicates a usage pattern and possible functionality that should be dropped.
Bugs are the indicator. They show you where to focus. Treat them as more than just a problem.
