Bug 399583

Application: baloo_file_extractor (5.48.0)

Qt Version: 5.11.1
Frameworks Version: 5.48.0
Operating System: Linux 4.18.11-200.fc28.x86_64 x86_64
Distribution: "Fedora release 28 (Twenty Eight)"

-- Information about the crash:
- What I was doing when the application crashed:
Trying to open an tar.xz package.

- Unusual behavior I noticed:
Baloo asked for restart. And it started consistently consuming 100% cpu resources.

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