normally the layout is the switzerland(german) one, but in the snapshot, when it comes to keybindings, y and z are swapped and the special characters are located somewhere else too

For me the bug only appears in 13w16a, so in the newest snapshot, where Mojang already uses an updated version of LWJGL

made a quick video showing a way to reproduce the bug
read my other comment for a way to solve this bug

It's a bug because "lastServer" always gets saved with a blank string in options.txt and the blank string always gets loaded when you start the game. The only thing missing is the communication between the class, wich handles the options.txt file and the one wich is the direct connect gui.
Fixing or doing the connection between them is just a little fix and possible in a very short time for the developers.

Why I don't add the server to the list is simple: it's not "one" server but many (only the subdomain changes). It's saves a lot of time when you don't have to edit the entry in the list, but only in the direct connect gui, but rewriting the whole address every time I start Minecraft really annoys me, so knowing it's a very small fix, wich can become really annoying I reported it.

This happens because the hopper only checks the first item it finds above. If that item can't go in, the hopper won't check for any other to pick up until the first found item is out of range.
A solution would be to iterate over the list of items in the boundingbox above the hopper until it finds one wich can go in. That way the hopper still would only take one item every update, but if there's an item above it can take, it'll take it.
