Description Thiago Sueto 2019-10-23 04:28:30 UTC 
SUMMARY
I have the full Kontact suite installed. I ran Kontact once, removed akonadi-backend-mysql and added akonadi-backend-sqlite, removed all configuration files, followed instructions from Arch Linux wiki to switch to SQLite backend (https://wiki.archlinux.org/index.php/KDE#SQLite), started Kontact, tried connecting to a Google Account unsuccessfully, went to Settings > Configure KMail > Accounts > Receiving > selected my Google account and pressed modify.

This causes a segmentation fault to akonadi_imap_resource (according to Dr. Konqi) that does not crash Kontact nor KMail, it just does not allow me to open the window for modifying the imap account.

I can modify Local Folders, however.

The Dr. Konqi popup appears reproducibly if you click on Restart and then Modify.

Comment 1 Thiago Sueto 2019-10-27 21:29:34 UTC 
I tested this bug on the Mysql backend. Apparently this happens regardless of using sqlite or mysql.
Comment 2 Thiago Sueto 2019-11-17 19:36:21 UTC 
No longer crashes on version 5.12.80 beta1 (19.11.80).
Comment 3 Thiago Sueto 2020-04-20 18:34:54 UTC 
I can no longer reproduce this crash on current master.
