Crash report not apearing

I can not get a crash report when the game crashes using the new launcher. I have been using mods and they keep crashing me and i would like to be able to view the crash report to see whats wrong, but i cant get it. I have tested in vanilla minecraft using the F3+c debug crash and i cant get a crash report there either.

The bug should be easy to reproduce. Simply play make the game crash (with F3+c for example) and notice that clicking on view crash report dose nothing
