Strange repodata/other.xml issue...

[Dmitry Butskoy]

Sometimes the changelog entries contain "<" and/or ">" symbols. For 
example, a fragment of the changelog of "k3b" package:

> * Wed Oct  6 02:00:00 2004 Harald Hoyer <harald at redhat.com> 0:0.11.17-1
> - version 0.11.17
> - revert the dao -> tao change
> - add the suid feature to every app automatically

note the "->" in the line:

> - revert the dao -> tao change

When I create my local repodata ("cd somewhere; createrepo ."), the 
correspond fragment appears in the "repodata/other.xml.gz" file, in the 
form of:

> - revert the dao -> tao change

Then, when I update my repodata by "createrepo --update .", I receive an 
error:

> Scanning old repo data

IOW, the initial "full" createrepo run seems OK, the subsequent run with 
"--update" is failed.

Any comments? Whether it is some bug in createrepo, or in some yum 
components?
