leveling up a skill as you spawn will rarely not give you that skill.

So very occasionally, if you level up your first skill as you spawn in (you shouldn't do this really I know, but its a bug regardless) you won't get the skill leveled and you won't have a skill point to level any skills, so you'll have zero skills at level 1. I don't know why it does this, its only happened to me twice, both times as Tryndamere leveling spinning slash at level 1. I didn't learn spinning slash and I lost my skill point. when you hit level 2 you get both skill points so it doesn't totally screw you. This isn't the biggest bug in the world. But it is relevant, and it has happened to me in a ranked game once, and once in a public game with my friends, so I thought I'd just let you guys know (it might only be a Tryndamere bug, its pretty rare, so its not easy to test- but I promise it is a real bug) And it can give you a pretty big disadvantage in lane if your versing an aggressive laner.
