Bug 406915

Application: kbibtex (eeff6135 (HEAD), near 0.9.50)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.27-gentoo-r1-resume_from_partuuid x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
I closed kbibtex and then it crashed. There was a file open which had just been edited by another program, but I had told KBobTeX to reload it.

-- Backtrace:
Application: KBibTeX (kbibtex), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
