Lightning 2.8b1 doesn't work with SeaMonkey 2.23 because it was not rebuild after landing the two fixes for Bug 927073. According to objdump the file libcalbasecomps.so still depends on "xul26.0" but the fixed libxul.so shipped with SeaMonkey announces only "xul26".
A later Lightning 2.8b1 test build doesn't show the problem anymore. I tested the one from <https://ftp.mozilla.org/pub/mozilla.org/calendar/lightning/tinderbox- builds/comm-beta-linux/1386568018/> build on 09-Dec-2013. In my opinion a Lightning 2.8b2 release would be required to support SeaMonkey 2.23 on Linux. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1244619 Title: Thunderbird must be upgraded to Thunderbird 24.0.1 for lightning 2.6.1 Status in Lightning extension: Confirmed Status in Mozilla Thunderbird Mail and News: Confirmed Status in “thunderbird” package in Ubuntu: Fix Released Status in “thunderbird” package in Gentoo Linux: Fix Released Status in “thunderbird” package in openSUSE: Fix Released Bug description: Since the upgrade of Lightning 2.6.0 to Lightning 2.6.1, this extension need Thunderbird 24.0.1 but Ubuntu only give Thunderbird 24.0.0 https://blog.mozilla.org/calendar/2013/10/dont-upgrade-to-thunderbird-24-0-1-yet/ "Update 4: Lightning 2.6.1 is now public.
