Bug#233812: Can't remove libxrender-dev

[Graham Knap <graham.knap@rogers.com>]

Package: libxrender-dev
Version: 0.8.3-5

I can't seem to uninstall this package. Here's what happens.

[root@supernova] ~# dpkg --purge libxrender-dev
(Reading database ... 54262 files and directories currently installed.)
Removing libxrender-dev ...
Removing `diversion of /usr/X11R6/lib/libXrender.a to 
/usr/X11R6/lib/libXrender-1.1.a by libxrender-dev'
dpkg-divert: rename involves overwriting `/usr/X11R6/lib/libXrender.a' with
  different file `/usr/X11R6/lib/libXrender-1.1.a', not allowed
dpkg: error processing libxrender-dev (--purge):
 subprocess post-removal script returned error exit status 2
Errors were encountered while processing:
 libxrender-dev
[root@supernova] ~#

Is this a bug in the package, or is my system just messed up?
If it's just my system, how can I correct it?

Thanks
