This bug also affects MythTV. I can also reproduce this using the test app. You obviously need to point it to a valid server and database for the bug to trigger. I'll attach a slightly modified version of the test app that allows you to change the DB credentials to a valid host, user, password and database.
The bug started to trigger after an update to libmysqlclient21 from 8.0.17 to 8.0.20. The server is Ubuntu Server 18.04.4 LTS. The client is on Kbuntu 19.10. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1877183 Title: segfault in mysql_server_end() from libmysqlclient.so.21 Status in mysql-8.0 package in Ubuntu: Invalid Status in qtbase-opensource-src package in Ubuntu: Invalid Bug description: libmysqlclient.so.21 causes a segfault on shutdown.
