Put the summary of the bug you're having here

*What I expected to happen was that the minecraft launcher would automatically download the resource pack via the minecraft server.

What actually happened was that after I clicked the *Yes button when the server ask me to download the resource pack automagically, following a quick 2 second load back to the launcher and said "uh oh, looks like the game has crashed!" During that it opened a crash report which I have no idea about this conundrum.

Steps to Reproduce:
1. Open Minecraft
2. Go on a server which says "The server recommends you to download this resource pack"
3. Click yes
4. After that it should be self explanatory.
5. You leave it to download and it crashs after 2 seconds.
