libc6 update problems

[Grahame White <grahame@regress.homelinux.org>]

I just tried doing an aptitude upgrade but I'm getting the following 
errors:

Unpacking replacement libc6 ...
dpkg: error processing /var/cache/apt/archives/libc6_2.3.5-3_amd64.deb 
(--unpack):
 trying to overwrite `/usr/lib64', which is also in package xmms-kde
Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)
Ack!  Something bad happened while installing packages.  Trying to recover:
dpkg: dependency problems prevent configuration of libc6-dev:
 libc6-dev depends on libc6 (= 2.3.5-3); however:
  Version of libc6 on system is 2.3.2.ds1-22.
dpkg: error processing libc6-dev (--configure):
 dependency problems - leaving unconfigured
dpkg: dependency problems prevent configuration of locales:
 locales depends on glibc-2.3.5-3; however:
  Package glibc-2.3.5-3 is not installed.
dpkg: error processing locales (--configure):

Press return to continue.

I'm using sid.

Has anyone else had the same?
