<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I thought I had fixed the semi-random crashes by moving the KDBusService creation to before the creation of most of the other objects on the stack, but it still happens for some reason.
The crash happens often, but not always, when instantiating KDBusService with KDBusService::Unique, and I have honestly no idea why it happens, but it happens in the cleanup of static data, I think?
The (almost useless) backtrace is like this, most of the time:

I'm fairly certain that it is not a bug in the konsole code, but we might be constructing something in the wrong order or something.
But in any case it doesn't really affect the functionality, except that it clutters up coredumpctl with useless coredumps.</pre>
