-------------------------------------------------------------
The previous tests were with mandriva 2008 & CUPS 1.3.6 (the results were the same with CUPS 1.3.5)

Now we test with Ubuntu (kernel 2.6.22.14)
For this distribution :
Port Monitor & CUPS work fine with CUPS 1.3.2
but
Segmentation fault also occurs with CUPS 1.3.6
