Arch Linux

This worked fine for me, so I don't know what your problem is. Is there any terminal output? Is there a link to an upstream bug where this is discussed? Anything?

about packge thunderbird-60.0-2-x86_64.pkg.tar.xz

Thunderbird crashed on two machines with the following message:
---
[calBackendLoader] Using Thunderbird's builtin libical backend
[1] 1512 segmentation fault (core dumped) thunderbird
---

I have similar issue (on Linux sarchx64 4.17.13-arch1-1-ARCH #1 SMP PREEMPT Mon Aug 6 23:06:31 UTC 2018 x86_64 GNU/Linux)

quite useless tracebacks on stripped binaries.

Also, tbird was updated to 60.0 but without the i18n languages!

Finally, if I start 'thunderbird --ProfileManager', I can create a new profile
and start if selected. I'll see if it's possible to manually migrate,
if not then arch should revert until 60.1 as it is unacceptable to lose email capability in the meanwhile.

As far as my situation goes, I found that tb-60 was intolerant of a certain subfolder name under "Local Folders".

Luckily I was able to track it down and delete it, now tb starts. Get that!
Perhaps, rokups@ has a similar situation.

Only need -i18n-fr now, and ASAP please.

@risto3 have you reproted your findings upstream?

very quickly added https://bugzilla.mozilla.org/show_bug.cgi?id=1482248

Same as @risto3 :
* tb60 was crashing, and I had in "Local Folders", files and sub-folders with accented characters (from fr locale)
* moved them to non-accented
* since, is tb60 ok
* @risto3: thanks for the tip

Upstream fix has landed, we should backport the fix.

I have a segmentation fault (core dumped) when I try to start Thunderbird 60.0-3. Downgrading back to 52.9 appears not to work since icu is updated too, causing libicui18n.so.61 no longer to be installable (by me).

Update: It works if I remove feeds with Swedish characters or accents in the names of them. This is not a world-breaking nuisance, but it's a nuisance.

I could not fix my profile even though i had no folders with special characters. Even newly rebuilt profile started failing soon after. If anyone is in same situation you can downgrade thunderbird by installing package from aur: https://aur.archlinux.org/packages/thunderbird-gtk2

Any version higher than 52 didn't work for me. Had to downgrade to 52.9.1-2 => `downgrader thunderbird`
