baloo hangs because it does not get enough memory by systemd. The supplied value is 512M. This is far to low (at least for my system). Reproducible: Always Steps to Reproduce: 1. restart baloo via systemd 2. baloo hangs 3. restart Actual Results: baloo hangs during indexing the files. Expected Results: baloo should finish until state idle. I reported this bug to kde. See: https://bugs.kde.org/show_bug.cgi?id=502641 There I gut the crucial hint.
Thanks for the report. I don't think you should close the upstream bug. That limit isn't set by us -- we don't modify the systemd unit at all. We *could* start modifying it as a workaround but it still needs to be resolved properly upstream.
