Bug#688068: libmodule-corelist-perl: error removing diversion

[Salvatore Bonaccorso]

Hi Cristian, Hi Gregor

I was neither able to reproduce the error by installing a squeeze
system, installing libmodule-corelist-perl. Then upgrade to wheezy and
purging libmodule-corelist-perl.

So it seems here there is 'spurious' /usr/share/man/man1/corelist.1.gz
lying arround ...

... and if I'm correct here the date 2011-08-10 is when the file was
created. This correspond around the day before 5.14.1-2 was uploaded
to experimental. perl 5.14.2-3 was then uploaded to unstable on
2011-11-13.

Cristian, did you have at some point perl installed from experimental?

As said I cannot reproduce the issue by toing a squeeze->wheezy
upgrade, and afterwards removing libmodule-corelist-perl.

Regards,
Salvatore
