Description Diogo Gomes 2019-09-18 04:28:57 UTC

Application: dolphin (19.08.1)

Qt Version: 5.13.1
Frameworks Version: 5.61.0
Operating System: Linux 5.2.14-1-default x86_64
Distribution (Platform): openSUSE RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to move a big quantity of  files/folders with ctrl+a and then moving them between split windows.

- Unusual behavior I noticed:
Dolphin closes or clicking ctrl+a or when moving the selected files/folders to the split window.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Bus error
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Nate Graham 2019-09-18 17:35:34 UTC

Crashing in Baloo or LMDB.

Comment 2 Stefan Brüns 2019-09-18 22:12:17 UTC

This is either a corrupted DB, or a bug in LMDB.

If it is a corrupted DB, only deleting the DB will help:

$> balooctl purge

If it is a bug in LMDB, so be it.

Comment 3 Diogo Gomes 2019-09-19 03:27:11 UTC

Thanks for your reply.

I think it was a corrupted database because after the issue disappeared after purge the db.

I should also mention that baloo5-file was not installed and could also been related.

Thank you again.
