Unable to build project (java.lang.NullPointerException) [message #1083091]

It's been a while since I've needed to work on a C++ project, but recently I've been trying to get back into it, by installing CDT. Now I'm not even getting the example Hello World project compiled, and I'm starting to suspect a bug rather than wrong settings.

My environment:
- Fedora 19, 64bit, kernel 3.10.4-300
- g++ (GCC) 4.8.1, GNU Make 3.82, GNU gdb (GDB) Fedora (7.6-32.fc19)
- Eclipse Kepler (manually installed)
- CDT 8.2
- Oracle Java 1.7.0_25

The problem:
I create a new C++ project, with the HelloWorld template. I chose the Linux GCC toolchain. The project is created, but no 'Binary' folder shows up. Only the 'src' folder. Also, in the Project Properties > C/C++ General > Paths and Symbols > Inludes, no includes or symbols show up (I thought this was supposed to work automatically).

So, initially, "#include <iostream>" and "cout" and "endl" show up as errors.
I can manually add the includes to Paths and Symbols to solve this.

Now, clicking the "Build Project" button, gives me this dialog:

Errors occurred during the build.
Errors running builder 'CDT Builder' on project 'HelloWorldCPP'.
Internal error building project HelloWorldCPP configuration Debug
java.lang.NullPointerException
Internal error building project HelloWorldCPP configuration Debug
java.lang.NullPointerException

And that's that.
Creating the project in a new workspace doesn't change a thing.

Would this be a CDT bug? Or something wrong with my setup or settings?

Thanks!

Wow, thank you so much.
Using the nightly build just works,

Actually I have this problem too.I imported a cocos2d-x project and it worked fine but i just restart eclipse and then this errors shows up.

I'm using these:

ADT Package 23.0.2.1259578
CDT 8.0.2.201202111925

and this is log:
