This does not appear to be a Mailman bug per se. I can see the problem with the .txt.gz files in the http://mail.gnome.org/archives/xslt/ archive, but I see this is a MHonArc archive, not a pipermail archive, and I don't know how the .txt.gz files are made in this environment. As noted, I am able to gunzip the .txt.gz file into a .txt file which is the full length, and if I then gzip that file with the Python 2.6.5 gzip module (which is the what standard GNU Mailman does) I get a result as follows: $ gunzip -l 2002-August.txt.gz compressed uncompressed ratio uncompressed_name 82840 380598 78.2% 2002-August.txt I get the same result with the gzip modules from Python 2.5.2 and 2.4.3. So, this appears to be a problem with whatever process produces the .txt.gz files from the .txt files in this particular installation's archive. I have also looked at some .txt.gz files in some other installation's archives, and they don't have this problem. ** Changed in: mailman Status: New => Invalid -- malformed digest archive https://bugs.launchpad.net/bugs/596764 You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman.
