Segmentation fault copying a file

[Eneko Nieto]

Hello,

I get a segmentation fault when I try to copy a file in particular:

$ cp a b
Fallo de segmentación

Note: "Fallo de segmentación" means segmentation fault.

$ ls -l
-rwx------ 1 eneko eneko  16875520 2007-08-14 12:55 b
-rwx------ 1 eneko eneko 102049992 2006-05-05 11:23 a

I am using Kubuntu Feisty 7.04.

Do you need more info? Perhaps a kernel bug?

Thank you very much and nice job!!
