Warning while upgrading tetex-extra 3.0-3 to 3.0-5

[Florent Rougon <f.rougon@free.fr>]

Hi,

I got this warning while upgrading tetex-extra 3.0-3 to 3.0-5:

Preparing to replace tetex-extra 3.0-3 (using .../tetex-extra_3.0-5.1_all.deb) ...
Unpacking replacement tetex-extra ...
dpkg: warning - unable to delete old file `/etc/texmf/lambda/config': Directory not empty

  % ls -l /etc/texmf/lambda/config
  total 4
  -rw-r--r--  1 root root 402 2002-10-13 04:07 language.dat

  % dpkg -S /etc/texmf/lambda/config/language.dat
  dpkg: /etc/texmf/lambda/config/language.dat not found.

Is it expected? Should I delete this file?...

Thanks.
