That's interesting about Lightning/Sunbird. Although, I've never installed an addon to Thunderbird. I have seen this problem for a few versions now using stock Thunderbird as downloaded for mozilla.org.
Perhaps adding and removing an addon coincidentally masks the bug away. Hopefully this will be helpful to someone that knows the thunderbird codebase to find the bug. -- new messages not able to type https://bugs.launchpad.net/bugs/271034 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
