You make it sound like the same bugs have been there for 25 years. That again isn't fair given that many, many, many new features have been added to the project since its inception in 2002. They are also somewhat at the mercy of the MLT framework that they depend on for a lot of the heavy lifting.

And they do fix crash bugs. All the time. You can see that in the announcements they put out after each release. I think the general perception is that it is indeed becoming more robust as time goes on as new developers have come on board to help. The project is gaining momentum that it hadn't really had before.
