The Message-ID header is broken over two lines with double anglebrackets in the Hyperkitty MBox linked above: Message-ID: < <153582973006.27514.7508703206376217479@alexandria.secretchronicles.org>>However, the original message as it was delivered by Mailman to me doesnot have such a weird message-id header: Message-ID: <153582973006.27514.7508703206376217479@alexandria.secretchronicles.org>In this message, the header is broken exactly as shown above after thecolon of "Message-ID:". Maybe some problem with parsing long Message-IDheaders, or ones folded over multiple lines?With regard to bug reporting on gitlab.com: I already have accounts on aton of sites, and at some point I'd actually like to stop creating newones all the time...Marvin-- Blog: https://mg.guelker.euPGP/GPG ID: F1D8799FBCC8BC4F
