The backtrace is unfortunately lacking debug symbols. Because of that we don't see exactly where it crashes. From what we see it looks like it crashes in QtDBus. If you are able to reproduce, please add a new backtrace with full debug symbols.

I was created this topic from the window on KDE when it crashes. So, this is regular crash. As i can see this is happend on intel processors with intel HD graphics. It can be after log in, or when i have a many opened windows. I can't tell exacltey what i do. But it periodically hapend. And this backtrace is full backtrace that i have, i tried to understand what is, but no luck. And this error was on 4 notebooks (msi,dell,acer,hp) and one desktop with core i5 and gigabyte MB. Starts from KDE 4 (i am forgot correct version). So, this is not a fake bug.
Sorry, "please install debug symbols" how can i do it on fedora 23 ?
by the way, this is not fedora error only, it was always on all popular destributives, i am updateing OS regular. So, i don't know what i can tell more. I just want help, if i can please tell me.
> how can i do it on fedora 23 ? Please ask in your distribution support channels. I don't know, but they should know.
