Bug 404237

Application: kmail (5.10.1)

Qt Version: 5.12.0
Frameworks Version: 5.54.0
Operating System: Linux 4.20.6-1-pae i686
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
Because I did not activate my debuginfo repository, I couldn't report earlier. Now that I have found out, some information will be lost (gone from memory).

- What I was doing when the application crashed:
Generally, configuring kmail on an new Tumbleweed System
Shortly before the first crash (while kmail was running), I had tried to configure Virus scanning in kmail, but since I forgot to install a virus scanner had to abolish. Closed the window instead of pressing the "finish" button.

Immediately before the first crash I was adding and removing local Maildirs.

Several attempts to start kmail were partly after a system restart, partly later while doing other things.

- What I did after the first crash
Because I thought the error might be in a "crashed" configuration, I deinstalled kmail, deleted some configuratiuion files and installed again, it didn't help.

- Unusual behavior I noticed:
When trying to restart kmail, and listening to internetradio simultaneously, the sound got broken.

----

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
