Comment 8 for bug 854622

Thanks for this additional file. This is interessting data. The md5sum of it is:
ce002095400b45d6a0a93bb03f065edf changelog.Debian.gz

But your .md5sum file expects:
680a0ae504d012f2e27adbc2def2c707 usr/share/doc/libglib2.0-0/changelog.Debian.gz

With a changelog from my system:
$ md5sum good-changelog.Debian.gz
680a0ae504d012f2e27adbc2def2c707 good-changelog.Debian.gz
$ diff -u changelog.Debian.gz good-changelog.Debian.gz
Binary files changelog.Debian.gz and good-changelog.Debian.gz differ

$ diff -u changelog.Debian good-changelog.Debian

-# For older changelog entries, run 'apt-get changelog libglib2.0-data'
+# For older changelog entries, run 'apt-get changelog libglib2.0-0'

So it appears like the libglib2.0-data changelog smuggled itself into the packages.
