SUMMARY https://cgit.kde.org/akonadi.git/tree/src/server/storage/dbconfigmysql.cpp#n360 ``` const QString confFile = StandardDirs::locateResourceFile("config", QStringLiteral("akonadi/mysql-global.conf")); ``` As far as I can tell that shouldn't have the akonadi/ prefix (as seen with other similar calls in that file). This seems to result in lookups going for $dir/akonadi/akonadi/mysql-global.conf which is wrong. Simply dropping the prefix should fix this problem as StandardDirs at a glance prefixes everything with akonadi/ forcefully. On a related note it may be a good idea to make StandardDirs either handle already prefixed arguments or raise an error.
