Steps to reproduce:
1. Clear your .minecraft folder
2. Head to the launcher, and while the resources are downloading:
a. Log-in using wrong account information (I used my MC username)
b. Log-in using right account information
This would be the result (after all resources finishes downloading):
Trying to log in...
Couldn't log in

Is this still a concern in the current Minecraft / Launcher version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
Fixed. Now either the launcher waits for the assets being downloaded or there is no bandwidth for authentification while downloading:

Uh, I just figured out that there is a launcher-only bug tracker, can a mod move it over?
