Crashes at message load after long idle time

[eyalroz]

I'm using 115.8.1-bb25 (64-bit) on Devuan GNU/Linux excalibur, with Cinnamon DE.

For the last couple of weeks (or so), I've been experiencing almost-certain crashes in the following scenario:

• App is running
• A long idle period (hours)
• Loading a message after the idle period (I think always the first one, but maybe sometimes the second one? Not sure)

I've experienced similar crashes, very infrequently, before, but now it's maybe half the times this scenario occurs, which is basically daily.

It sounds like Issue #266. What happens if you set these prefs to false:
mail.biff.show_tray_icon, mail.biff.show_tray_icon_always, mail.minimizeToTray ?

[eyalroz]

@Betterbird : I'll set these to false for a few days and see what happens, but the second two were already false.

[Betterbird]

Same issue as Issue #153, right? We never got to the bottom of this one. There were a few crash stories, all related to the system tray. The reports were that if people got back to the program after a while, reading a message and hence updating the system tray icon tooltip, it crashed. This happened on Gnome, but we can't rule out that Cinnamon is also affected.

Whoops... I'd forgotten I'd filed that one. I guess sometimes a few mysterious reports add up into something actionable. Will put a calendar reminder to report about the experiment results in a few days.

I'm getting crashes too. It happens only after I first start Betterbird after a boot/reboot. I'm not using the system tray feature.

Hmm, and TB doesn't crash? Have you switched these prefs off? mail.biff.show_tray_icon, mail.biff.show_tray_icon_always?

Fedora, Gnome and Wayland are really not the most stable combination. TB has crashes, too.

[beeburrt]

Thunderbird doesn't crash.

mail.biff.show_alert -- false
mail.biff.show_tray_icon -- false
mail.biff.show_tray_icon_always -- false
mail.minimizeToTray -- false

I installed the eu.betterbird.Betterbird.Debug but I'm sorta lost as to what to do next in order to attach gdb. Do I need to launch Betterbird from gdb before crash?

[Betterbird]

The FlatPak maintainer once pointed me to this article:

@beeburrt You can either

1. run Betterbird from gdb, then trigger the crash:

flatpak run --devel --command=sh eu.betterbird.Betterbird
gdb /app/lib/betterbird/betterbird
(gdb) run

2. or inspect previous crashes:

coredumpctl
flatpak-coredumpctl -m <PID from coredumpctl output> eu.betterbird.Betterbird

In both cases you should end up with a gdb prompt at the point where the crash occurred. From there you can save the C++ and the JS traces to a file by running:

(gdb) set logging file trace.txt
(gdb) set logging enabled on
(gdb) bt
(gdb) print DumpJSStack()

[beeburrt]

when I run:

flatpak run --devel --command=sh eu.betterbird.Betterbird

I get the cool betterbird prompt that looks like:

[📦 eu.betterbird.Betterbird ~]$

and then, after a few seconds, I get thrown back to my prompt, which I then have to reset to get back to normal

And when I run:

flatpak-coredumpctl -m 3627 eu.betterbird.Betterbird

I got:

Executable /usr/libexec/xdg-desktop-portal doesn't seem to be a flatpaked application.
Running: `"flatpak" "run" "--filesystem=home" "--filesystem=/tmp" "--command=gdb" "--devel" "eu.betterbird.Betterbird" "/usr/libexec/xdg-desktop-portal" "/tmp/tmpb2zscnka"`

...then gdb downloading more stuff... and then:

I realize this isn't really a betterbird issue at this point and I appreciate y'all, thanks.

@Betterbird : I'll set these to false for a few days and see what happens, but the second two were already false.

I think this took care of the crash issue for me.
