If I have this issue, where should I find this database, and where can I send
it for debugging? I had to disable indexing on Kubuntu 18.04.1 because they
apparently never applied this patch. Maybe it’s applied in 18.10, which I
recently installed. I’d still like to know if it’s a corrupt database.

Git commit f57c4bc27b81f2b40d910d376a0bb531cd8472c6 by Stefan Brüns.
Committed on 03/05/2018 at 22:37.
Pushed by bruns into branch 'master'.

Avoid infinite loops when fetching the URL from DocumentUrlDB

Summary:
Some users apparently have DBs which contain infinite loops in the idTree
(a parentId pointing to itself or one of its children). This manifests in
either crashes due to exhausted memory and/or the process being stuck
with 100% CPU load.

The problem can only be completely solved by either recreating the DB, or
by cleaning the DB from any problematic records. As in interim solution,
stop the code from crashing.

If I exclude the brk syscall from the strace you can see that basically
baloo_file_extractor is only calling `mmap` followed by `munmap` syscalls:

$ sudo strace -p 15018 -f -e \!brk
