SUMMARY

KMail crashes reproducibly for me whenever a file dialog is shown, but only for
2-5 times after I rebooted my PC, afterwards it's fine.

I have the same problem with other KDE Applications an Firefox, but decided to
file it here, because it's the most reproducible and most annoying to me.

It seems to me this crash is strongly related to Wayland, because it didn't
happen on X11.

STEPS TO REPRODUCE
1. Freshly booted my system
2. Open KMail
3. Go to "File" -> "Open"

OBSERVED RESULT

KMail crashes with the attached backtrace.

EXPECTED RESULT

KMail doesn't crash and I can select a file to open.
