OK, thanks for the update, Bryn. I think there is enough information in this report now that it can be send to the programmers. For their ease, I will add a summary here. Please feel free to add any corrections.
----------------------- SUMMARY: Ubuntu version 18.04 Thunderbird 52.9.1 (from Ubuntu 18.04 repository) Problem is reproducible by the bug reporter. Problem is evident when there are duplicate messages. Steps to reproduce: 1. Start Thunderbird 2. Set view to "Threads with Unread" 3. Attempt to read through messages (bug most easily triggered with busy mailing lists, for instance the zfs-discuss list) 4. Some message threads cannot be expanded, appears to be related to threads with duplicate messages Expected behaviour: all expansion “arrowheads” should expand the thread when clicked. Actual behaviour: the expansion “arrowheads” for duplicate messages will not expand the thread when clicked. Additional notes: ----------------------- Bug triager is unable to reproduce the bug.

In the attached image there are several threads that clicking on the '+' sign has absolutely no action. I cannot click the green circle to mark the messages as read either. This doesn't happen ALL the time, but seems to happen in particular when duplicate messages are delivered (in this case a yahoo! groups mailing list that occasionally sends duplicates) ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: thunderbird 3.0.4+nobinonly-0ubuntu4 ProcVersionSignature: Ubuntu 2.6.32-22.33-generic 2.6.32.11+drm33.2 Uname: Linux 2.6.32-22-generic x86_64 NonfreeKernelModules: fglrx Architecture: amd64 Date: Thu May 20 15:22:39 2010 ProcEnviron: PATH=(custom, user) LANG=en_CA.utf8 SHELL=/bin/bash SourcePackage: thunderbird To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/583577/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
