Using kMail and kOrganizer Version 5.3.0 (QtWebEngine), KDE Frameworks 5.25.0, Qt 5.7.0 (built against 5.7.0), The xcb windowing system from KDE Neon, I created an incident for which I invited several people. Actually, I invited some email distribution lists, so the invitations were spread out to other email addresses. Some receipients use Thunderbird and confirmed the incident. kMail crashes immediately as soon as I click at the mail in the mailing list and kMail tries to open it in the preview window. Unfortunately, I cannot provide a test case, as kMail does not seem to crash if it cannot find a link to the calendar incident. (If I modify the message to reference another indicent UID, the crash does not seem to happen.) I'm also having a hard time generaring a meaningful backtrace, as I could not find packages with debug symbols in my KDE Neon package lists - I'd probably need the developer edition, but I only installed the stable users' edition... :-/ Currently, I do not even seem to be able to get a partial stacktrace, only the information that kMail caused a segmentation fault... "Application: KMail (kmail), signal: Segmentation fault" :-( Reproducible: Always

You generated with korganizer right ? Do you have option to use compatibility outlook ?
* The incident was generated using kOrganizer. * It was accepted by an Thunderbird client, the attached resulting confirmation mail was generated by Thunderbird. * I'm not sure if and how I can configure Outlook compatibility options in Thunderbird - I'm not normally using it. I only used it to try to reproduce the crashes I experienced when trying to open confirmation mails generated by other Thunderbird users. On my system, it's sufficient to open the attached message in kMail and it will crash immediately.
Outlook invitations crash kmail/kontact as soon as the offending email is clicked on. openSuse Tumbleweed kmail5 16.08.0-1.2 I've added a sanitized email that triggers the crash. Mark
