Bug 404508

Application: baloo_file_extractor (5.55.0)

Qt Version: 5.12.0
Frameworks Version: 5.55.0
Operating System: Linux 4.15.0-45-generic x86_64
Distribution: KDE neon User Edition 5.15

-- Information about the crash:
Every time a restart baloo (bacause of file extractor crashing), after deleting the index data base, file extractor crashes in a couple of minutes; it seems that this happens always when indexing the same file because the number of files indexed when the crash happens is always the same

The crash can be reproduced every time.

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