Sentry Crash Report:

Description wincak 2018-02-01 07:00:38 UTC 
Application: elisa (0.0.80)

Qt Version: 5.10.0
Frameworks Version: 5.42.0
Operating System: Linux 4.14.15-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Opening settings. For the first time the dialog opens without problems, after closing and opening again the program crashes.

- Custom settings of the application:
I have added a webdav folder on my Nextcloud server to the list of indexed folders.
(Maybe the fact that you can add a network folder to "local files indexer" is a separate bug?)

The crash can be reproduced every time.

-- Backtrace:
Application: Elisa (elisa), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".

Comment 1 Matthieu Gallien 2018-03-26 20:05:41 UTC 
Thanks for your report. Sorry to have taken so long time to answer.

I did several changes related to this code in order to try to fix it.

I seem to be unable to reproduce it anymore (at least with the flatpak KDE build).

Could you check if you still get this crash ?
Comment 2 Matthieu Gallien 2018-03-26 20:08:22 UTC 
Sorry, I had not understood that NEEDSINFO closes the bug.
Comment 3 Matthieu Gallien 2018-04-26 19:22:22 UTC 
Could you test if you can still reproduce. I believe this bug is fixed.
Comment 4 wincak 2018-05-01 10:27:47 UTC 
Finally got back my computer and yes, can't reproduce this crash with version 0.1 anymore.

Thanks!
