--- Comment #1 from stefan.schwar...@gmx.net --- This is a section of the .xsession-errors which is associated to one of the 'random' freezes during a session (which would freeze also some applications where some = Mathematica which would then start working again after a restart of plasmashell. The SEARCH is from akonadi/kdepim which I know to have taken place before the first freeze. Maybe it helps.
