Blender crashes when using "Extrude individual faces"

Hello !
First of all excuse my bad English.
I’m new to Blender and started experimenting with different features of the program.
My problem is:
I start Blender and delete the cube. Then I use Shift + a to create a UV-Sphere.
Now, when i switch to edit mode and press alt + e and then use “individual faces”,
Blender crashes.
And this crash is reproducible. Everytime the program crashes.
There is no error message after the crash. When i click on “individual faces”
there instantly is no Blender window anymore.

If it helps to locate the cause of this crash, here some information on my system:

  • AMD Athlon 64 X2 6000+
  • 2 GB DDR2-Ram
  • Geforce 9600 GT (OpenGL version string: 3.3.0 NVIDIA 310.44)
  • OS: LUbuntu 13.04

I’ve deleted and reinstalled Blender and the problem is still there.

Thank you for reading this post !
I hope you can help to solve this problem.

bexactly the same thing happens to me in Ubuntu.
