I too experience this problem, but there were no logs to look for that I could find and it happened intermittently - apparently whenever I would login remotely hours before and come back to my desktop to try to logout days later :) or plugin an MTP device via dolphin. Finally found someone on KDE Forum https://bugs.kde.org/show_bug.cgi?id=463557 that investigated further. I have just removed those two profile.d files for now, and posted a note on opensuse forums for anyone else.
