Might be related to #198419 ? I've Kontact/Kmail 5.2.3 Whenever trying to add a filter or go to filter settings and modify it, then Kontact crashes. I've deleted filters and re-created it all, but still crashes I have 8 mailboxes, and all filter applies to either all or some All actions in filters are to move email to folder on receiving Also have Bogo spam filter added in the list, even though it never worked, really (have to select and remove my spam manually) Éric, annoyed.
This is probably unrelated to bug 198419, because a big deal of KDE PIM has been ported, rewritten,... since that was filed. Alas, it is very hard to impossible to find the cause of your crashes without a backtrace. Would you please provide one?
Closing due to lack of feedback
