There is already a package for unstable which unfortunately was taged
before this. It is 3.64-1 thus the unstable version does not contain a
note on this in the changelog.

I will try to prepare also a fixed versions.

Hi

As discussed with Giuseppe Iuculano on IRC on #debian-it I updated the
debdiff as needed, removing myself again from Uploaders and updating
the remaining changelog accordingly.

The current debdiff is attached, for the lenny version (etch version
is still missing).

Bests and thanks for reviewing

Package: libhtml-parser-perl
Version: 3.64-1

Hi Raphael

For unstable this bug a fix was included in the 3.64-1 upload.
upstream fixed it in 3.63-1, and 3.63-1 was prepared in pkg-perl svn.
Since there was no upload, this was included in 3.64-1 and uploaded
before this bugreport was reported. Thus closing manually.
