Bug 425266

Application: baloo_file_extractor (5.68.0)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-42-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:

Crashes every time indexing starts. I have not yet tried re-indexing completely in case there's useful state to extract. 

The only file showing as failed is an innocuous looking text file from the chromium snap: /home/bli/snap/chromium/common/chromium/pnacl/0.57.44.2492/_platform_specific/x86_64/pnacl_public_pnacl_json

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Extractor (baloo_file_extractor), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
