Description of problem:
After fresh installation almost all of the plain text file types (configuration files, logs, source code, ordinary text files, etc) are associated with the Libreoffice Writer in KDE systemsettings. So they opens in the Writer on a doubleclick instead of plain text editor like KWrite or Kate.
Version-Release number of selected component (if applicable):
Mageia-6-rc-x86_64-DVD.iso with KDE Plasma installed.
