Description Christian Nitschkowski 2020-06-14 12:08:24 UTC

SUMMARY
Akonadi indexing agent crashes time and again, even without any user interaction without any special configuration.

STEPS TO REPRODUCE
1. Login into Plasma session.

OBSERVED RESULT
When I login to KDE session the crash report dialog pops up during login.
While the session is running a toast message will pop up every now and then telling me the indexing agent crashed.

EXPECTED RESULT
The indexing agent shouldn't crash.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 32 
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.70
Qt Version: 5.13.2

ADDITIONAL INFORMATION
I upgraded from KDE 5.16 to 5.17 to 5.18 without resetting my configuration. The problem occurred already with KDE 5.16. It first came up a few days after setting up my computer and persisted over several updates.

The crash can be reproduced every time.

Please add the backtrace from the crash dialog. For more information, please see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Comment 3 Christian Nitschkowski 2020-07-08 05:59:25 UTC

Attached the backtrace

Comment 4 Christoph Feck 2020-07-08 08:17:13 UTC

Seems to be an unhandled exception in Xapian.

Comment 5 Christian Nitschkowski 2020-08-04 21:50:13 UTC

Is there any way to stop that indexing error to appear time and again?
It is really annoying and gets to a point I'm actually thinking about switching to a different DE because I get those crash notificiations every few seconds.
