I really appreciate the aurora project and I know that here isnt really the right place to bring up this topic. But I couldn't think of a better because as far as I know Aurora is the only base theme which focuses this much on stuff like compass and grunt driven frontend development. So I started to build up my Aurora sub theme and ended up in a WSOD. It took me days to find out the source of that appearance because as we all know a WSOD doesnt tell you very much about it. But finally after renaming the subtheme I found out that there is a problem in the subtheme which cant be solved by renaming it. The small problem is called 'lcov.info' and a part of the grunt-karma extension. After deleting this file, everything works find again.
But that brings me to my point. Shouldnt there be a way to prevent a .info file from making such a big mess? Probably it would be better to address this issue somewhere else but my suggestion is that very likely in the Aurora theming environment some one else might step in the same trap as I did.
