Bug 403013

Application: baloo_file (5.53.0)

Qt Version: 5.12.0
Frameworks Version: 5.53.0
Operating System: Linux 4.19.11-1-default x86_64
Distribution (Platform): openSUSE RPMs

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

I had just booted the computer up and logged in, I did notice this morning plasma had failed to start and so it booted my out to my command prompt. When I had started it up this afternoon it seemed to work fine, not sure what happened but it must've sorted itself out.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
