I recently observed tons of baloo_file_extr segfaulting in dmesg. Is this a known bug? Or should I file a bug Is there a known way to fix? Although, I am not unhappy, if this thing does not generate loads of I/O on my disk all the time :D

A couple of things that have worked for me when I have had problems with Baloo (sefaulting or 100% CPU on one core) are given in the following post:
Clevo W230SS: amd64 nvidia-drivers & xf86-video-intel.
Compal NBLB2: ~amd64 xf86-video-ati. Dual boot Win 7 Pro 64-bit.
OpenRC eudev elogind & KDE on both.

Fitzcarraldo thanks, as your tips removed the segfaulting. Strange enough, it also re-enabled my printer being visible within cups. I was already considering it dead, as it would not print within a KVM VM either. After disabling, and enabling balooctl followed by the deletion of mentioned files in linked bugreport, I rebooted and found no segfaults anymore. To my surprise printer was recognized again and started doing its job :D
