  A x = b

  So problems appear when A matrix fill of zeroes, and a few nonzero  
elements, and the right side also a few nonzero elements? Or the right  
side doesn't matter? If you have any matrix that might fail, write it  
here, so I'll try to make a testcase from it.

  The testFuzzySpase testcase was intented to test such problems, see here:

  Strange.. It seems that this test somehow didn't made it to Julian's  
kde4-port branch.
