1674991 - Thunderbird crashes after 78.4 Update (w/OpenPGP)

Status: RESOLVED INCOMPLETE

(MailNews Core :: Security: OpenPGP, defect)

Description

[ulf.treger]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:82.0) Gecko/20100101 Firefox/82.0

Steps to reproduce:

I started Thunderbird this morning. A message in an extra tab is shown, showing me that Thunderbird has been updated and asking me to migrate from Enigmail to the new GPG/PGP module (?). I started the migration, at the end, I gave permission to restart as asked. Before there is a message, that some of my keys could not be imported. (Unfortunately the keys are only named by a lengthy hash, so i couldnt identify them)

After restart, the password for Thunderbird is requested, I type in the password and submit. Then I can see the Thunbird UI, a second tab with an opened message. After a sec and before I can click on anything Thunderbird is closing. No messages are shown, the screen is just gone.
Starting w/STR (Safe mode) does not make a difference, Thunderbird crashes.

Actual results:

Thunderbird crashes. I cant work with it any more.

Expected results:

Thunderbird starts normally

No crash report? https://support.mozilla.org/en-US/kb/mozilla-crash-reporter-tb

Thanks for asking, I forget to mention, that there is no visible crash reporter. In %APPDATA%\Thunderbird\Crash Reports\ there is only one file (with timestamp of today), called InstallTime20201019003438, its contents is just a bunch of numbers: 1604322938 and an empty subdir called "events"

I could help me out by creating a new profile (and re-importing) the old profile to make Thunderbird run.

I could narrow down the problem: Actually it was the second tab with an message, which has been PGP encrypted. That causes the crash.

Even after I reseted the session settings and could work with Thunderbird (because the 2nd tab is not opened at start up anymore), the moment I select another encrypted message, Thunderbird closes instantly without any error message (same behaviour as described before).

I've checked and redone the Enigmail migration. No success.

We need the crash id, which you should be able to find under Help | Troubleshooting information

Hi Magnus, thanks for asking. As mentioned before, the strange thing is, that there are no crash reports. I just reproduced the problem, then checked Help > Troubleshooting > Crash Reports: There are no crash reports. Same is if I look up %APPDATA%\Thunderbird\Crash Reports\

Nothing we can do without a crash report. Please reopen if you get one.
