So, when I authorize and click the timeline, -- the "ThunderBird" (v52.9.1) waits (a bit) -- and -- crashes... I -- tried to see: what -- happens through a "Safe Mode"? -- and -- saw that: ``` "thunderbird -safe-mode" -- terminated by signal SIGSEGV (Address boundary error) ``` Any ideas? If you won't help -- I will think about redirecting it to a "Linux Manjaro" main forum. They -- could face it the same way, as I do (as having the same "Linux Manjaro" software distribution). On some other "Linux" distribution (one of those; can't remember, on which -- exactly: "Linux Mint 19", "Fedora 28") -- it worked correctly. Thank you.
