-- Information about the crash:
After enabling a plugin (probably adblock), the program stopped launching upon restart. When the kdepim-addons package is removed, KMail starts normally. However, with the kdepim-addons package installed, KMail crashes every time.

The crash can be reproduced every time.

Comment 2 wanio1ster 2025-05-20 12:03:09 UTC 
I found a plugin that crashes KMail, it's kmail_checkfoldersizeaccount.
After activating it, KMail shows:
KCrash: Application 'kmail' crashing... crashRecursionCounter = 2
Segmentation fault (core dumped)
