Thunderbird Segmentation Fault after update 11.03.2025 V128->V136

[Zauberer-Merlin]

Am I the only one experiencing seg faults when starting thunderbird after the update today?

V128 works - god made timeshift even before he did build the world I believe

I tried to

• manually export the profile and import it into V136
• start without extentions/themes
• start in “safe mode”

I can open the profile manager, I can start thunderbird with a new empty profile, but as soon as I try to setup a new email account it is crashing with a segmentation fault.

Will continue to search for a solution ( later today or tomorrow - now I need to work with mail access), probably in any thunderbird forum, but I was just wondering whether I would be the only one experiencing this

Hi @Zauberer-Merlin,

I don’t know whether you’re the only one, but do believe that’s the AUR one or something and unsupported. Because mine works flawlessly, albeit without email account, and mine is installed from the extra repository, and is version 128.8.0esr:

$ pamac search thunderbird
[...]
thunderbird  136.0-1 [Installed]                                                                                                                                                                                            extra
Standalone mail and news reader from mozilla.org
$ pamac info thunderbird
Name                  : thunderbird
Version               : 128.8.0-1
[...]

However, this:

thunderbird  136.0-1 [Installed] 

…is confusing.

[Zauberer-Merlin]

it’s definitly not AUR, i work with pacman -Syu…

But - I checked as well - and indeed it is … at least confusing:

pamac search -i thunderbird                                      ✔ 
thunderbird  136.0-1                                                       extra
    Standalone mail and news reader from mozilla.org

as well as

Thunderbird → about:

128.8.0esr (64-Bit)
Neue Funktionen und Änderungen
Mozilla Thunderbird for Manjaro LinuxManjaro - 1.0

strange …

[Mirdarthos]

I guess it was a simple mistake as Firefox is:

$ pamac info firefox
Name                  : firefox
Version               : 136.0-1
[...]

Edit:

But seeing as we use the same version, after all, I think your problem is probably something in your profile, or an extension, or both. You can try removing the .thunderbird directory and see what happens:

mv ~/.thunderbird ~/.thunderbird.backup

[Zauberer-Merlin]

ok - so there is any bug in the mirrors, correct?

sudo pacman -Sc
sudo pacman-mirrors -f

No, just a mistake, or whatever you want to call it in the version numbering of the package. That actually has nothing to do with the mirrors.

[Zauberer-Merlin]

hm … I (at the moment) do not believe it is an profile issue … not an extention one … but I might be wrong …

ok - understood - so I will just ignore this “update” for the time being.

THanks for your help - appreciated

I can not wait … I could but this is so hard for me …

I did

• move the .thunderbird to .thunderbird.backup
• uninstall thunderbird
• install thunderbird and german language pack via pacman

It starts. I setup a new account. As soon as this account tries to connect to the IMAP server it crashes

However, this:

thunderbird  136.0-1 [Installed] 

…is confusing.

I think adding a Thunderbird language pack might change the perceived version (language packs are currently @ 136.0-1); though I don’t understand why that should be the case.

pamac search thunderbird also reveals this on a recently built VM, and I know it was the “esr” (128.x.x) that I installed.

thunderbird  136.0-1 [Installed]
    Standalone mail and news reader from mozilla.org

Edit:-

Pacman says differently, however:

pacman -Qs thunderbird
local/thunderbird 128.8.0-1
    Standalone mail and news reader from mozilla.org

Maybe it’s a pamac quirk of some kind.

---

But to the main item on the agenda;

There have been many reports of segfaults in recent weeks attributable to nothing specific. It’s quite possible Thunderbird isn’t the culprit here; unfortunately, I don’t know what is.

[Mirdarthos]

Welp, I don’t use it for email. In fact, I have that tab hidden. I only use it for Cal- and CardDav, so wouldn’t get this error.

But, try another server, or even protocol and see if it still happens? That way you might be able to narrow it down a bit more.

[Zauberer-Merlin]

I did try the same without language pack installation - same errors and same version mismatch

[Zauberer-Merlin]

switching off all Gnome Shell extentions let’s thunderbird 136 start

Now it’s getting boring … switching one by one off just to figure it out wtf it is …

Edit says:

• in order to use Thunderbird 136 one needs to disable the Gnome Shell Extention “Top Bar Organizer”
