Description Gerhard Dittes 2020-03-03 16:02:55 UTC

Thunderbird crashes when trying to write an email.

This happens right after clicking on the "write" button -- but only if enigmail is enabled! 

"Opening" the corresponding new window (for writing) might be the cause, as this should actually lead to update the global menu entries.

(It also happens when trying to respond to an email.)

I've raised the severity to major, as not being able to write encrypted emails could have critical impact (at least for some people).


STEPS TO REPRODUCE
1. Open Thunderbird
2. Enable enigmail extension
3. Click on "write" button

OBSERVED RESULT

Crash of (whole) Thunderbird.

EXPECTED RESULT

New window should be opened in order to be able to start writing.

Report to thunderbird

Hi David,

I guess you've overseen something. Thunderbird works quite fine in every situation (and on every desktop (and OS)).

It only crashes if one makes use of Plasma's "Globel Menu" widget. (If you don't use the widget and stay with vanilla Plasma, everything's fine!)

I don't think that non-KDE developers develop against an extension of Plasma, do you? ;-)

Imho, whatever the reason might be, "Global Menu" widget should be improved to not cause other applications to crash.

Regards, Gerhard

It doesn't.

Plasma's global menu is not a plugin running inside thunderbird, it is an interface that the thunderbird process talks to over DBus.

If thunderbird crashes it is code running inside thunderbird with the mistake. It is not our bug, we cannot fix it.

All right, thanks! I've meanwhile created a corresponding bug report over there:
