Application: baloo_file (5.18.0)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-53-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed: opening a .doc file with lock override. About 10 minutes after a full restart and with the system running cleanly, attempted to open a file; the file had been locked previously (about1 year ago) and I had to to override the lock. LibreOffice opened the file normally but Baloo crashed immediately.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
