When trying to modify an IMAP account via kmail Settings -> Configure Kmail -> Accounts Then try to click 'Modify...' on 'IMAP Account 4' (the only imap mail account), nothing happens. In the system journal, I can see that akonadi_imap_resource has crashed. Dump below. $ rpm -qa | grep -i Akonadi | sort akonadi-1.13.0-103.fc26.x86_64 akonadi-import-wizard-17.04.1-1.fc26.x86_64 kf5-akonadi-calendar-17.04.1-1.fc26.x86_64 kf5-akonadi-contacts-17.04.1-1.fc26.x86_64 kf5-akonadi-mime-17.04.1-1.fc26.x86_64 kf5-akonadi-notes-17.04.1-1.fc26.x86_64 kf5-akonadi-search-17.04.1-1.fc26.x86_64 kf5-akonadi-server-17.04.1-3.fc26.x86_64 kf5-akonadi-server-mysql-17.04.1-3.fc26.x86_64 kf5-kmailtransport-akonadi-17.04.1-1.fc26.x86_64 kf5-libkdepim-akonadi-17.04.1-1.fc26.x86_64 kf5-mailimporter-akonadi-17.04.1-1.fc26.x86_64 kf5-pimcommon-akonadi-17.04.1-1.fc26.x86_64 $ rpm -qa | grep -i kmail | sort kf5-kmailtransport-17.04.1-1.fc26.x86_64 kf5-kmailtransport-akonadi-17.04.1-1.fc26.x86_64 kmail-17.04.1-1.fc26.x86_64 kmail-account-wizard-17.04.1-1.fc26.x86_64 kmail-libs-17.04.1-1.fc26.x86_64 akonadi_control[1868]: org.kde.pim.akonadicontrol: ProcessControl: Application "/usr/bin/akonadi_imap_resource" stopped unexpectedly ( "Process crashed" ) akonadi_control[1868]: org.kde.pim.akonadicontrol: Application '/usr/bin/ akonadi_imap_resource' crashed.
