Crash when clicking on the multiplayer button, new launcher (1.6.11)

My minecraft suddendly crashed (on old laucher) and it asked me to use the newest. I downloaded it, it works correctly i launch it all is fine. But when i click on multiplayer it crashes, every time. So anyone have the same problem or i'm alone? Please answer me quickly i can't join my friends now with this launcher. If this problem was already reported don't blame me, i searched about this problem and i didn't saw it.

It was supposed to open ther server list.

When i click on multiplayer button it crashes.

Steps to reproduce:
1. Launch minecraft
2. Click on the play button
3. click on multiplayer buton when you are on the menu.
