Description Julian Schmidt 2016-11-19 08:03:34 UTC 
Application: baloo_file (5.18.0)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-47-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
Whenever I start a VirtualBox VM the Baloo daemon crashes. Consistent behaviour for several weeks now. I have Win 7 as a guest OS, but the crash happens immediately when I hit the start VM button.  Random crashes happen without VM use, too. But not as regular.

The crash can be reproduced every time.

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

Comment 1 Julian Schmidt 2016-11-22 07:37:08 UTC 
the crash also happens when I copy/create a file with dolphin. Seems like a general HD access problem.

My home file system is on a NFS share. Maybe that is relevant.

New crash information added by DrKonqi

baloo_file (5.44.0) using Qt 5.9.5

- What I was doing when the application crashed:

This happens just about every time I boot up and login to a Plasma desktop session, right after login before I even click on anything.

That's in Baloo::DocumentDB::del(), which is different, and tracked with Bug 405284.

As for this issue in IdFilenameDB::del(), there have been no duplicate bug reports seen in over three years. After all the bugfixing work done during that time, I think we can call this fixed!

Comment 14 Nate Graham 2020-10-26 16:27:59 UTC 
Duped a report of this happening in 5.71, but that was confirmed fixed on git master as of a few months ago. Not re-opening unless we get a new report against 5.75 or later.
