Bug ID: 425266
Summary: baloo_file_extractor crashing repeatedly when indexing
starts
Product: frameworks-baloo
Version: 5.68.0
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: Baloo File Daemon
Assignee: stefan.bru...@rwth-aachen.de
Reporter: benjun...@gmail.com
Target Milestone: ---
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".
