I see exactly the same thing using Fedora-23.  
Balloo is identified as:
$ rpm -qf /usr/bin/baloo_file_extractor
kf5-baloo-file-5.19.0-1.fc23.x86_64

I am running Firefox with an unusually larger number of windows+tabs
Windows: 14, Tabs: 58, which seems to affect system performance.
Comment 4 Edward Donovan 2016-06-07 03:34:34 UTC
My experience under Kubuntu 16.04 is just the same.  
  Plasma 5.5.5
  Qt 5.5.1

I believe it's been happening for a while under at least Kubuntu 15.10 as well; I forget what Plasma & Qt versions that might have been.  

My backtrace may not add anything, but drkonqi usually suggests it's no use, and this time it liked it for a change.  (I'm not adding this via drkonqi because it got stuck when I tried to mark my report as a dupe.  Oh well.)  Thanks.

Hi, how large is your

.local/share/baloo/index

file?

Comment 7 José Gonçalves 2016-09-12 09:08:39 UTC
Hi,
I restarted baloo so I do not know if the size is the same when the
program crashed.
Right now the size is 5.0 GB.
And the infor in balooctl status is:

Baloo File Indexer is running
Indexer state: Indexing file content
Indexed 120536 / 204025 files
Current size of index is 992.07 MiB

Thanks
José

Comment 8 Christoph Cullmann 2016-09-12 09:09:59 UTC
Ok, then you are soon screwed again :/

You need at least git master, as baloo will kill itself after 5GB

(see already the wrapped output in status)

Current size of index is 992.07 MiB
Comment 9 Edward Donovan 2016-09-13 00:39:37 UTC
Pardon me if this isn't needed, or should be on the the bug this is duped to --

Same here, my ~/.local/share/baloo/index is 5.0G.

Thanks for looking at this, Christoph.
