--- Comment #2 from Øystein Olsen <dr.scient at gmail.com> ---
I have the same issue with kmail 18.08.3.
Qt version: 5.11.2
Framework: 5.52.0
OS: OpenSUSE Tumbleweed.
I believe this back-trace should be more useful:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
28 return SYSCALL_CANCEL (nanosleep, requested_time, remaining);
