Bug 356114

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.

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.

Backtrace of the crash I experienced:

Hi, how large is your

.local/share/baloo/index

file?

*** This bug has been marked as a duplicate of bug 367480 ***

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

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

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.
