Description Igor Zhuravlov 2025-01-11 03:52:59 UTC 
Created attachment 177275 [details]
PNG file which crashes baloo_file_extractor with SIGSEGV

SUMMARY
baloo_file_extractor not indexes a PNG file attached.

STEPS TO REPRODUCE
1. Place a file attached to any folder which the Baloo is configured to index.
2. Or run `balooctl index` explicitly.

OBSERVED RESULT

> balooctl index /home/user/tmp/ic_folder_black_18dp.png
Indexing /home/user/tmp/ic_folder_black_18dp.png
File(s) indexed

> balooctl failed
The following files could not be indexed:
/home/user/tmp/ic_folder_black_18dp.png

EXPECTED RESULT
File must be indexed without problems, so `balooctl failed` command should output nothing.

> baloo_file_extractor not indexes a PNG file attached.
I'm not able to reproduce - although I'm trying on more recent systems. I've tested on Neon Unstable which has frameworks 6.11.0 and
Fedora 40 that has Frameworks 6.5.0

There's always a chance that you've got a corrupt file, you can check with the PNG validator:
    http://www.libpng.org/pub/png/apps/pngcheck.html
However I've looked at the attached file and it seems OK (this is with F40...)
    $ pngcheck ic_folder_black_18dp.png 
    zlib warning:  different version (expected 1.3.0.zlib-ng, using 1.3.1.zlib-ng)
    OK: ic_folder_black_18dp.png (18x18, 16-bit grayscale+alpha, non-interlaced, 84.7%).

You can see what Baloo has indexed with
    $ balooshow -x ic_folder_black_18dp.png
and confirm that it only has a single version indexed
    $ baloosearch -i ic_folder_black_18dp.png
If baloosearch returns more than one hit, then something else is wrong...
Comment 2 Igor Zhuravlov 2025-01-11 08:22:05 UTC 
The problem now is gone: this PNG file was indexed ok. What I've done:
1) simplified the Baloo config - reduced excluded directories list to a few;
2) purged the Baloo index DB;
3) rebooted PC.

Thank you for hints!
