See subject line, its fussing about:
kbuildsycoca4(20256) KConfigGroup::readXdgListEntry: List entry MimeType in "/root/.local/share/applications/wine-extension-jpeg.desktop" is not compliant with XDG standard (missing trailing semicolon).
Fussing about the whole list, about 100 files I'd guess. Some have the trailing semi-colon, some don't, but my adding it to a specific file doesn't seem to shutup the squawk about that particular file.
This is 'wall' blasting every open terminal I have, essentially rendering the machine ususable because it overwrites the contents on the screen, of any file you might have open in the editor, vim or gedit.
As this seems to run at about 2 minute intervals, I have to synchronize and get all of an edit done before kbuildsycoa4 restarts again.
I have a 15 day uptime, so I'll chance a reboot.
