Description:
The new dovecot package, rebuilt for MariaDB 10.3.x causes auth-worker to fail:

From /var/log/mail.log:

I have reported this upstream and received a patch that fixes the problem.
Please decide if it's good enough to be used in our repository package until an official fix comes from upstream.
Until then, I'm going to use the patch anyway.

Additional info:
0 « root » /etc/dovecot # pacman -Q mariadb dovecot
mariadb 10.3.12-3

Hopefully the patch can be included in the current package
The patch can be found here https://github.com/dovecot/core/commit/3c5101ffdd2a8115e03ed7180d53578765dea4c9.patch

I have added the upstream patch to the package, please test the fixed package located here:

pacman -U https://www.foxxx0.de/pkgs/dovecot-2.3.4-3-x86_64.pkg.tar.xz

When using pacman with that URL it will also fetch the gpg signature and validate it, that package is signed with my official Arch Linux TU key.

Please report back if this package fixes your issues and then I will commit it to the repository.

Running the test build for half an hour, and not seeing segfaults any more. Looks like this is the fix, thank you!
