I'm trying to write a testcase for the second set of tracebacks, but I'm having a hard time understanding where the message that causes it comes from. When I open the pickle file I get: 'From nobody Sat Mar 23 09:42:34 2013\n\n' This goes through the digest runner and tracebacks at line 269 with "TypeError: decoding Unicode is not supported" Do you know where such a message can come from ? Are you OK with just writing a test case with this string as an entry message ? -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1130957 Title: Unicode errors in mailman3 To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1130957/+subscriptions
