[opensuse-kde] KMail keeps changing theme of the list of the messages

Since about a week, KMail 5.5.3 (Tumbleweed) keeps when starting changing theme of the message list to "Intelligent" (default). I must change it manually (View | Message list | Theme) to "Classic", which I set long time ago and keep it as required. Anyone else having same problem? How to tell KMail not to change my choice? -- Vojtěch Zeisek Komunita openSUSE GNU/Linuxu Community of the openSUSE GNU/Linux https://www.opensuse.org/ https://trapa.cz/
