kde-baloo crashes

[Rens Oliemans]

Hi all,

kde-baloo crashes at each execution when run via systemd (stacktrace &
versions below). I've tried running /usr/lib/kf6/baloo_file directly, but
that is taking hours and hours. It's still running - let me know if you want
its output.

I've done a clean Arch install two days ago, and have installed KDE Plasma
on it. (Though I don't think it's too relevant, that went somewhat
unorthodox: I first installed 'plasma-meta' and 'kde-applications-meta', but
soon found that 'kde-applications-meta' included too much for my liking and
uninstalled that with 'pacman -Rs kde-applications-meta'. Since then, I've
installed some specific packages. If you want more information, please let
me know.)

Below is the stacktrace as reported by Crashed Processes Viewer (drkonqi). I
now have four of these stacktraces, and for some reason the size of one of
these coredumps is 10M, where the other three are ~950K.
