One of the nice things about Open Source programs is that you can squash the bugs that bite you. Of course, not everyone is able to do that, but still. And though there is no obligation to do so, it is nice if you share your patches with the rest of the world.
Sometimes, though, the sharing part just does not work out. I recently encountered two such cases, where I tried to do the right thing but my patches will probably never be used.
