Description cmdr.splash 2022-01-01 07:42:34 UTC

Application: digikam (6.4.0)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.11.0-43-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Initial scan of 52GB Photos, 270GB Videos. Previously in another instance of Digikam, tags written to file. On initial run to build database program closed unexpectedly several times, once taking down entire Plasma GUI. Was able to "sudo shutdown -r" from TTY4. Upon re-opening program seems happy to continue where it left off. Twice it unexpectedly "Jumped" from reporting ~65% progress to 100%, but on re-start it continued from 65%. Something crashed there. There are a number of tags written into the files already.

The crash can be reproduced sometimes.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Hi,

Definitively, it's a packaging problem, as this kind of crash have been fixed since a while from the tags engine cache. Forget Ubuntu packages and take the Official Linux AppImage bundle that we provide from 7.x releases. We recommend to cleanup the database files (probably corrupted) or to restore an older backup, and start from scratch with 7.5.0 pre-releasse bundle available here :

https://files.kde.org/digikam/ 

Have an happy new year
