I file my fair share of bugs.  Generally I like to post issues to discussion groups (mailing lists) to be sure there is indeed an issue and that I am not overlooking something.

Lets see where this discussion goes and then I/we can determine if it warrants a bugzilla entry.

When I was working on the issue I never once thought that I was dealing with a bug.   Could fdisk and (g)parted be made better ?  Yes.  Are they buggy ?  No.
