Bug ID: 400498
Summary: baloo_file crashed a few minutes after starting Plasma
Product: frameworks-baloo
Version: 5.51.0
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: Baloo File Daemon
Assignee: baloo-bugs-n...@kde.org
Reporter: matthew.fagn...@utoronto.ca
Target Milestone: ---
Application: baloo_file (5.51.0)
Qt Version: 5.11.1
Frameworks Version: 5.51.0
Operating System: Linux 4.18.16-300.fc29.i686 i686
Distribution (Platform): Fedora RPMs
-- Information about the crash:
- What I was doing when the application crashed:
baloo_file crashed about 5 minutes after I logged into Plasma in Fedora 29. I
was using Konsole and Firefox at the time although these are likely unrelated
to the crash.
I installed the kf5-baloo*-debuginfo-5.51.0-1.fc29 ,
qt5-qtbase-debuginfo-5.11.1-8.fc29, lmdb-debuginfo-0.9.22-3.fc29,
glibc-debuginfo-0:2.28-9.fc29 packages.
I've seen similar crashes in baloo_file many times in previous KF5 versions
which usually occur about 5-30 minutes after starting Plasma.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Aborted
Using host libthread_db library "/lib/libthread_db.so.1".
