Comment 11 Laurent Montel 2022-01-06 19:06:31 UTC

Git commit 06848bf8d9685858fc348d9ab0f7a5a998264918 by Laurent Montel, on behalf of Nicolas Fella.
Committed on 06/01/2022 at 19:00.
Pushed by mlaurent into branch 'master'.

Don't access KMKernel when destructing KMReaderMainWin

At this point the kernel is already deleted by KMailPart, so we are accessing a nullptr.

Since we know which config we want to access we can do that directly.
