That's not really an accurate message, but I guess it depends on how you define "crash". I generally think of crashing in the sense that the program completely stops running due to a segfault or something. That's just an error that shuts the map down. I don't think it should be removed, because it lets you know the map (or ent file) is messed up. All you need to do is test your ent file before uploading it to the server. If it just loaded the map anyway, things wouldn't be correct, and it would be harder to tell why.
