            Bug ID: 367874
           Summary: kMail crashes upon Thunderbird-generated invitation
                    confirmations
           Product: kmail2
           Version: Git (master)
          Platform: Neon Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: kdebugs at CustomCDROM.de

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
