Segmentaiton faults on a fresh Kubuntu 6.06-1 install

[Jon Grant]

Hello,
Not sure if this is the place to discuss the segmentation faults I have
experienced, but I dont have enough info to file a bug report.

I've installed Kubuntu 6.06-1 Desktop from ISO.

I am experiencing two SIGSEGV, my other programs are ok, Firefox, X, and
KDE etc run without any crashes. I've been using this PC for about 4
days now. The crashes are reproducible.

I verified the md5sums on the libc packages and also coreutils. I
rebuilt the latest coreutils and got the identical crash.


The two programs which I use which cause the seg faults are "dd" and
"smbpasswd"

Any suggestions and help welcome,

Kind regards
Jon



I thought about reinstalling coreutils, but I got this warning, any
ideas why that has started happening? I've enabled universe and
multiverse, and no other apt sources..

apt-get install --reinstall coreutils
