The real value of posts like this one is that they are, literally, frequently asked questions (just take a look at the list of linked questions for the example question above if you don't believe me), and thus serve as useful targets for closing any duplicates of them that get regularly re-asked.
In particular, note that, if this question were closed (or, worse yet, deleted), we'd suddenly have literally dozens of duplicate questions linking to a question which is itself closed.
Ideally, such questions should be edited to clean them up and to make them clearly focused on the core of the issue. In this particular case, the question already is quite clean and focused; the only major complaint seems to be that it's short, but that shouldn't be seen as a problem in itself, if there question still provides enough information to clearly specify the problem.
In short, IMO, this is not a poor question. It wasn't that when it was asked, and it still isn't — the only reason a question like it should be closed, if asked today, is that it'd be a duplicate. Furthermore, having this question on SO fulfills a very useful function as a target for closing any new duplicates of it.
